🚀 What's New in v4.2.0
✨ Highlights
- Offline Camera OCR & Screenshot Extraction: In-keyboard live camera viewfinder with top flash control and gallery picker, plus 1-tap screenshot text extraction. Includes advanced formatting (casing, join styles, punctuation, dehyphenation), auto-copy, and auto-insert.
- Real-Time Inline Math Suggestions: Live calculation on typing
=(e.g.25*4=,500-15%=) with immediate suggestion strip answers and 1-tap replacement. - Sound Packs Suite & Plugins Hub: Dedicated Sound Settings with 12+ built-in presets, remote GitHub catalog downloads, physical modeling packs, unbundled assets for a lighter APK footprint, and custom
.zipimports.
🐛 Bug Fixes & Refinements
- OCR Plugin Lifecycle: Dynamic ClassLoader invalidation and timestamp validation to prevent native library lookup errors during plugin reload.
- Typing & Auto-Capitalization: Improved multiline auto-capitalization in chat apps, restored fast double-tap on Shift for Caps Lock, suppressed emojis during gesture typing, added case-matching autocorrect safeguards, and supported immediate text expansion when backspacing into shortcuts.
- UI & Toolbar Polish: Swipe-down gesture anywhere on the toolbar to close keyboard, centered micro-pill indicators, and improved dynamic contrast on Material You light themes.
- Audio, Haptics & AI Safeguards: Added haptic feedback on key repeat for Backspace/arrow keys, handled missing microphone permissions gracefully, added toast notifications when AI output is truncated, and auto-cleaned legacy sound packs.
