Stop resetting history navigation on input so editing recalled entries doesn't wipe the bottom draft. Allow ArrowDown navigation while in history and persist the session draft only for fresh prompts.
Extract prompt draft/history, attachments, picker, and keydown logic into co-located hooks. Introduce PromptInputApi for quote/expand/setText and migrate SessionView off DOM poking; remove legacy registerQuoteHandler.
Converts hardcoded UI copy to i18n keys across the app, adds global translation for non-component modules, and splits the English catalog into feature modules with duplicate-key detection.
- Remove isMobileWidth signal and updateMobileWidth resize listener
- Use same placeholder text for all devices/platforms
- "Type your message, @file, @agent, or paste images and text..."
Simplifies implementation per dev feedback - one approach for all
- 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
