Reverse the message stream scroll layout so the viewport naturally starts at the newest messages and keeps older content virtualized. Use sentinel-based edge chasing to make jump-to-top/bottom land reliably despite VirtualItem mounts.
Allow pointer interaction with the message preview tooltip and delay hover dismissal so users can move from the timeline segment onto the preview to copy or delete.
Remove the redundant header row, tighten spacing, and square off question cards. Also adjust answered question container styling to match tool call layout.
Use a dedicated --text-on-accent token for accent chips/checkmarks and tweak task list item surfaces so task/todo renderers keep contrast in dark mode.
Use tokenized border contrast so dark mode borders stay subtle, keep instance tab status dots vivid in dark themes, and adjust tool-call code block header background via a dedicated token.
Add a 3-state theme toggle in folder selection and instance tabs, and update tokens/styles so light mode has readable contrast. Sync MUI surfaces and Shiki highlighting to CSS variables to prevent stale colors when switching themes.
- Remove 3-state logic (normal/50%/80%) - now only normal/expanded
- Remove double-click detection and tooltips for simplicity
- Remove platform-specific behavior (same UX for Electron and web)
- Optimize button layout: reduce from 36px to 28px to fit 3 buttons
- Position expand button above history buttons in vertical stack
- Keep 15-line expanded height (360px, capped to available space)
Per upstream dev feedback to keep it simple with one approach
- Add platform detection (Electron vs Web) for expand behavior
- Electron: 3-state (normal → 50% → 80%) with double-click
- Web/Mobile: 2-state (normal → expanded) with instant single tap
- Implement fixed 15-line height for web/mobile (360px, capped)
- Add orientation-aware height calculation (landscape vs portrait)
- Remove tooltip on web/mobile, keep for Electron desktop
- Add responsive placeholder text to prevent overlap on mobile
- Desktop: "Type your message, @file, @agent, or paste images and text..."
- Mobile (≤640px): "Type message, @file, @agent..."
- Delete dev-docs/expand-chat-input.md per upstream feedback
Addresses PR feedback to simplify from 3-state to 2-state for web/mobile
while maintaining rich desktop experience in Electron app.
- Add expand button with Maximize2/Minimize2 icons
- Implement 3-state height management (normal/50%/80%)
- Smart double-click detection with 300ms delay
- Height calculation based on session-view - 200px message space
- Custom CSS tooltip with dark gradient background and backdrop blur
- Send button anchored at bottom via margin-top: auto
- Smooth CSS transitions throughout
- Double-click at 80% now reduces to 50% (not normal)
- Removed all debug console.log statements
