+
+### 🎯 Current Focus: Quality of Life & Polish
+**Next Up:** Implementing high-impact QoL features to reduce friction and improve user experience - starting with Toast Notifications, Command Palette, Auto-save, Drag & Drop, and Chat Search.
+
+**Recent Completion:** Chat Branching/Checkpoints - Full conversation branching system allowing users to create and explore alternate conversation paths from any message point. Each branch maintains its own complete message history with a branch manager modal for easy navigation.
+
+## Phase 1: Core Roleplay Infrastructure (High Priority)
+**Goal: Enable basic roleplay-focused prompt engineering**
+
+### 1. World Info/Lorebook System ✅
+- [x] Create UI for managing lorebook entries (keyword, content, priority)
+- [x] Implement keyword detection in recent messages
+- [x] Add context injection before message generation
+- [x] Support recursive entry activation
+- [x] Per-character lorebook assignment
+- [x] Import/export lorebook files
+
+**Why Important:** World Info is the foundation of consistent roleplay. It allows dynamic context injection based on what's currently relevant in the conversation, saving tokens while maintaining world consistency.
+
+### 2. Author's Note ✅
+- [x] Add configurable Author's Note field (inserted at depth 1-5)
+- [x] Position control (after system, before/after examples, etc.)
+- [x] Per-character Author's Note support
+- [x] Template variables in Author's Note
+
+**Why Important:** Author's Note is considered better than system prompts for roleplay because it appears closer to the actual conversation, reducing AI tendency to ignore or forget instructions.
+
+### 3. Jailbreak Templates ✅ (Implemented as Prompt Presets)
+- [x] Add jailbreak template field in settings (Prompt Presets with system additions)
+- [x] Preset jailbreak templates for roleplay (Built-in presets: Default, Roleplay, Creative Writing, Assistant)
+- [x] Per-character jailbreak override option (Active preset per character)
+- [x] Template preview and testing (Editable instruction blocks with live preview)
+
+**Why Important:** Many roleplay scenarios require specific prompting to work well with API safety filters and to maintain character consistency.
+
+## Phase 2: Enhanced Character Features (High Priority)
+**Goal: Better character representation and user identity**
+
+### 1. User Personas ✅
+- [x] Create persona management UI (name, description, avatar)
+- [x] Chat-level persona locking
+- [x] Character-level persona locking
+- [x] Default persona setting
+- [x] Quick persona switching
+
+**Why Important:** Allows users to have multiple identities for different roleplay scenarios without manually changing their name and description each time.
+
+### 2. Character Expressions/Sprites
+- [ ] Support for emotion-based character images
+- [ ] Sentiment analysis of AI responses (local model)
+- [ ] 28+ emotion presets (happy, sad, angry, neutral, etc.)
+- [ ] Expression sprite packs (import/export)
+- [ ] Manual expression override with /emote command
+- [ ] Sprite positioning options (beside chat, behind chat, etc.)
+
+**Why Important:** Visual representation of character emotions dramatically enhances immersion and makes conversations feel more alive.
+
+### 3. Message Examples in Context ✅
+- [x] Actually use mes_example field from character cards
+- [x] Format and inject into prompt properly
+- [x] Position control in context
+- [x] Token budget allocation for examples
+
+**Why Important:** Message examples help the AI understand the character's voice and writing style, leading to more accurate portrayals.
+
+## Phase 3: Advanced Chat Management (Medium Priority)
+**Goal: Non-linear conversation control**
+
+### 1. Chat Branching/Checkpoints ✅
+- [x] Save conversation state at any message
+- [x] Create branches from any point
+- [x] Switch between branches
+- [x] Visual branch indicator in UI
+- [x] Branch naming and organization
+- [x] Delete branches
+- [ ] Merge branches (deferred - nice to have)
+
+**Why Important:** Roleplay often involves exploring "what if" scenarios. Branching lets you explore different conversation paths without losing previous progress.
+
+### 2. Enhanced Message Controls ✅
+- [x] Delete individual messages (not just clearing all)
+- [x] Regenerate any message (not just last)
+- [x] Continue incomplete messages
+- [x] Message pinning (keep certain messages in context)
+- [x] Message folding/hiding
+- [ ] Bulk message operations (deferred - nice to have)
+
+**Why Important:** Fine-grained control over conversation history allows users to craft the perfect roleplay session.
+
+### 3. Timeline Visualization
+- [ ] Visual tree of chat branches
+- [ ] Quick navigation between branches
+- [ ] Branch metadata (creation date, message count, etc.)
+- [ ] Visual diff between branches
+- [ ] Merge branch capability
+
+**Why Important:** Makes managing complex branching conversations intuitive and prevents users from getting lost.
+
+## Phase 4: Multi-Character/Group Chats (Medium Priority)
+**Goal: Enable complex multi-character scenarios**
+
+### 1. Group Chat Foundation
+- [ ] Create group chat data structure
+- [ ] UI for managing group members
+- [ ] Add/remove characters from groups
+- [ ] Group chat history management
+- [ ] Per-group settings
+
+**Why Important:** Many roleplay scenarios involve multiple characters interacting. Group chats enable DM-style gameplay and complex social scenarios.
+
+### 2. Reply Management
+- [ ] Manual character selection
+- [ ] Natural order (mention-based)
+- [ ] Talkativeness settings per character (0-100%)
+- [ ] Auto-mode (characters respond automatically)
+- [ ] Character muting/unmuting
+- [ ] Reply order presets
+
+**Why Important:** Gives users control over conversation flow while allowing for spontaneous multi-character interactions.
+
+### 3. Group Chat UI
+- [ ] Character indicators on messages
+- [ ] Character list sidebar
+- [ ] Mute/unmute controls
+- [ ] Character ordering/priority
+- [ ] Group-wide lorebook support
+
+**Why Important:** Clear visual indicators make group conversations easy to follow.
+
+## Phase 5: Context & Token Management (Medium Priority)
+**Goal: Visibility and control over context usage**
+
+### 1. Token Counter ✅
+- [x] Real-time token count display
+- [x] Per-section breakdown (system, history, WI, etc.)
+- [ ] Visual context budget indicator (deferred)
+- [ ] Dotted line showing context cutoff in chat (deferred)
+- [ ] Warning when approaching limit (deferred)
+
+**Why Important:** Understanding what's in context and what's being cut is crucial for debugging issues and optimizing prompts. Core functionality complete - visual enhancements can be added later.
+
+### 2. Context Templates
+- [ ] Customizable prompt assembly order
+- [ ] Handlebars template support
+- [ ] Presets for different model types (Alpaca, ChatML, Llama, etc.)
+- [ ] Template preview
+- [ ] Variable substitution visualization
+
+**Why Important:** Different models expect different prompt formats. Templates ensure prompts are formatted correctly for each model.
+
+### 3. Smart Context Management
+- [ ] Summarization of old messages
+- [ ] Automatic message trimming
+- [ ] Priority-based context allocation
+- [ ] Context budget per source (system, WI, history, etc.)
+- [ ] Smart message selection (keep important messages)
+
+**Why Important:** Efficient context usage means longer, more coherent conversations without running out of tokens.
+
+## Phase 6: Power User Features (Low Priority)
+**Goal: Advanced customization and automation**
+
+### 1. Quick Replies
+- [ ] Preset message buttons
+- [ ] Macro support in quick replies
+- [ ] Import/export QR sets

+### 1. Instruct Mode Support
+- [ ] Preset templates (Alpaca, ChatML, Llama, etc.)
+- [ ] Custom template creation
+- [ ] Auto-detect model format from API
+- [ ] Instruction wrapping for system/user/assistant messages
+
+**Why Important:** Ensures compatibility with instruction-tuned models that expect specific formats.
+
+### 2. Export/Import Improvements
+- [ ] Export chats as markdown
+- [ ] Export chats as formatted text
+- [x] Export chats as JSON with metadata
+- [x] Import chats from other formats

+**Goal: Reduce friction, improve feedback, and enhance overall user experience**
+
+### 1. Toast Notification System
+- [ ] Create toast component (bottom-right positioning)
+- [ ] Success/error/info/warning variants
+- [ ] Auto-dismiss with configurable timeout
+- [ ] Queue multiple toasts
+- [ ] Hook into all major actions (save, delete, import, export, etc.)
+
+**Why Important:** Users currently have no immediate feedback when actions succeed or fail. Toasts provide instant visual confirmation without blocking workflow.
+
+### 2. Command Palette
+- [ ] Ctrl+P to open command palette modal
+- [ ] Fuzzy search for all actions
+- [ ] Keyboard navigation (arrow keys, enter, escape)
+- [ ] Recent/frequent actions at top
+- [ ] Show keyboard shortcuts in results
+- [ ] Categories (Chat, Character, Settings, etc.)
+
+**Why Important:** Power users want keyboard-first workflow. Command palette dramatically speeds up common actions without memorizing shortcuts.
+
+### 3. Auto-save & Recovery
+- [ ] Auto-save unsent message in input field
+- [ ] Restore unsent message after app restart
+- [ ] Draft system for in-progress edits
+- [ ] Session recovery (restore scroll position, open panels)
+- [ ] Crash recovery with last known state
+
+**Why Important:** Losing work due to crashes or accidental closes is extremely frustrating. Auto-save provides a safety net for all user work.
+
+### 4. Drag & Drop Support
+- [ ] Drag character card PNGs to import
+- [ ] Drag lorebook JSON files to import
+- [ ] Drag chat history JSON to import
+- [ ] Drag images to set as character avatar
+- [ ] Drop zone overlay with visual feedback
+- [ ] Support for multiple file drops
+
+**Why Important:** Drag & drop feels natural and is much faster than navigate-click-select workflow. Modern desktop apps are expected to support this.
+
+### 5. Search in Chat History
+- [ ] Ctrl+F to open search bar
+- [ ] Highlight all matches in messages
+- [ ] Navigate between results (prev/next buttons)
+- [ ] Case-insensitive search
+- [ ] Search counter (e.g., "3 of 42 matches")
+- [ ] Clear search and restore view
+
+**Why Important:** Long roleplay sessions can span hundreds of messages. Finding specific content without search is tedious and time-consuming.
+
+### 6. Context Menus (Right-Click)
+- [ ] Right-click messages for actions (edit, delete, regenerate, branch, copy)
+- [ ] Right-click character dropdown for quick actions
+- [ ] Right-click World Info entries for edit/delete
+- [ ] Right-click in message input for paste/clear/templates
+- [ ] Context-aware menu items
+
+**Why Important:** Right-click is muscle memory for desktop users. Faster than hovering to reveal action buttons.
+
+### 7. Better Feedback & Confirmations
+- [ ] Confirmation dialogs for destructive actions (delete character, clear chat)
+- [ ] Loading spinners for API calls
+- [ ] Progress bars for file imports
+- [ ] "Saving..." / "Saved" indicators
+- [ ] Success messages for completed actions
+
+**Why Important:** Users should never wonder if an action succeeded or is still processing. Clear feedback prevents confusion and repeated clicks.
+
+### 8. Undo/Redo System
+- [ ] Undo message edit (Ctrl+Z)
+- [ ] Undo message delete
+- [ ] Undo character field changes
+- [ ] Undo World Info changes
+- [ ] Action history panel (optional)
+- [ ] Redo support (Ctrl+Shift+Z)
+
+**Why Important:** Mistakes happen. An undo system provides a safety net and encourages experimentation without fear of losing work.
+
+### 9. Settings Search
+- [ ] Search bar at top of settings panel
+- [ ] Fuzzy search across all setting names and descriptions
+- [ ] Highlight matching settings
+- [ ] Collapse/expand sections based on matches
+- [ ] "Recently changed" section
+
+**Why Important:** With 22+ features, finding specific settings is tedious. Search makes configuration much faster.
+
+### 10. Character Management Enhancements
+- [ ] Recent characters quick-switch dropdown
+- [ ] Character search/filter by name or tags
+- [ ] Character folders/categories
+- [ ] Duplicate character (as template)
+- [ ] Favorite/star characters
+- [ ] Sort options (name, date created, last used)
+
+**Why Important:** Managing 10+ characters becomes messy. Better organization tools scale with user's character collection.
+
+### 11. Enhanced Keyboard Support
+- [ ] Full keyboard navigation in all modals (Tab, Arrow keys, Enter)
+- [ ] Escape to close any open panel/modal
+- [ ] Vim-style navigation mode (optional, j/k for scroll)
+- [ ] Keyboard shortcut hints on hover
+- [ ] Focus indicators for keyboard navigation
+
+**Why Important:** Keyboard navigation should work everywhere. Current implementation is inconsistent across different UI sections.
+
+### 12. Export/Share Enhancements
+- [ ] Export conversation as formatted HTML
+- [ ] Export conversation as formatted PDF
+- [ ] Export as markdown with proper formatting
+- [ ] Copy conversation to clipboard (formatted)
+- [ ] Export individual messages
+
+**Why Important:** Users want to share and archive conversations in readable formats, not just JSON.
+
+### 13. Accessibility Improvements
+- [ ] ARIA labels for all interactive elements
+- [ ] Screen reader support
+- [ ] High contrast mode option
+- [ ] Larger click targets option (accessibility mode)
+- [ ] Reduced motion mode (respect prefers-reduced-motion)
+- [ ] Focus indicators for keyboard navigation
+
+**Why Important:** Accessibility makes the app usable for everyone, including users with disabilities. It's also often legally required.
+
+### 14. Better Visual Feedback
+- [ ] Smooth transitions for panel open/close
+- [ ] Hover states for all interactive elements
+- [ ] Active state indicators (focused panel)
+- [ ] Better empty states with helpful text
+- [ ] Skeleton loaders for content loading
+- [ ] Micro-animations for actions (delete, save, etc.)
+
+**Why Important:** Visual polish makes the app feel responsive and professional. Small animations provide context for state changes.
+
+### 15. Smart Defaults & Templates
+- [ ] Scenario templates (fantasy RPG, sci-fi, modern, etc.)
+- [ ] Pre-filled World Info templates
+- [ ] Character card templates
+- [ ] Quick-start wizard for new users
+- [ ] Import from popular character repositories
+
+**Why Important:** Reduces friction for new users and speeds up common tasks. Templates provide starting points for customization.
