🚀 What's New in v4.1.9

✨ New Features

• Offline Camera OCR & Screenshot Text Extraction: In-keyboard live camera viewfinder with top flash control and gallery picker, plus an automatic screenshot suggestion pill ([OCR] [Screenshot] [X]) for 1-tap text extraction. Includes advanced text formatting (casing transformations, single-line/paragraph joins, dehyphenation, punctuation normalization, bullet stripping, whitespace/noise filtering), auto-copy, and auto-insert.
• Real-Time Inline Math Suggestions: Live mathematical evaluation on typing = (e.g. 25*4=, 500-15%=, (12+8)/4=) with immediate suggestion strip answers and 1-tap in-place replacement. Configurable via Settings -> Text correction -> Inline math calculation.
• Sound Packs Suite & Plugins Hub: Dedicated Sound Settings screen under the Plugins Hub with 12+ built-in presets (iOS, Mechanical Cherry MX, Thocky, Typewriter, CRT, Bubble Pop, Velvet, Wood, Marimba, Modern Tick, Sci-Fi, 8-Bit Arcade), remote GitHub catalog downloads, physical modeling packs, unbundled assets for a lighter APK footprint, and custom .zip pack import.

🐛 Bug Fixes & Improvements

• Typing & Auto-Capitalization:
  • Improved auto-capitalization in chat apps and multiline fields after newlines (#448).
  • Restored fast double-tap on Shift to reliably lock Caps Lock.
  • Suppressed emoji suggestions during gesture/glide typing to avoid cluttering predictions (#470).
  • Explicitly finish composing text and commit words on IME editor actions (Enter / Next / Done).
  • Added case-matching autocorrect safeguards to prevent learned capitalized words from replacing regular words mid-sentence (#477).
  • Supported immediate text expansion when backspacing into shortcuts (#476).
• UI & Toolbar Polish:
  • Reliable swipe-down gesture anywhere on the toolbar to close the keyboard via dispatchTouchEvent.
  • Upgraded toolbar long-press indicators from asymmetric dots to centered micro-pills with 25% contrast.
  • Guaranteed high-contrast dynamic colors on Material You light themes (#479).
  • Unified screenshot and OCR suggestion chips into a compact pill layout with tight spacing.
• Audio, Haptics & Voice:
  • Enabled haptic feedback on key repeat for Backspace and navigation arrow keys (#473).
  • Prevented crashes and gracefully handled missing microphone permissions / audio initialization failures (#466).
  • Auto-cleanup legacy sound pack directories on duplicate re-import.
• OCR & Stability:
  • Cached and retained PluginClassLoader singleton in OcrPluginLoader to prevent UnsatisfiedLinkError on native .so reloads.
  • Enforced explicit LayoutParams height on OCR camera views to eliminate viewport expansion during keyboard resizing.
  • Scoped screenshot observers strictly to active keyboard sessions to optimize battery and thermal footprint.
  • Added truncation safeguards to AI prompts to prevent data loss and ensure clean prompt fallback (#472).
