🚀 What's New in v4.2.6

✨ Highlights

• Floating Window Layout & Dead Space Resolution: Completely eliminated the persistent bottom dead space inside the floating keyboard window. By intercepting Android 15/16 window insets dispatch, dynamically disabling fitsSystemWindows on floating subviews, clamping occupied heights during measure passes, and performing a deferred re-measurement after layout transitions, the floating bubble now hugs key rows seamlessly with zero extraneous padding.
• Flavor Consolidation (standardfull Merged into standard): Successfully finalized the flavor streamlining announced in v4.2.5. The legacy standardfull flavor has been merged directly into standard. LeanType is now officially published as two clean, focused flavors (standard and offline), both operating with zero REQUEST_INSTALL_PACKAGES permission overhead. Existing standardfull users can install the standard APK directly as an in-place upgrade.
• TYPE_NULL & Dialer Search Field Input: Resolved an issue where input fields configured with TYPE_NULL (such as phone dialer search inputs and generic app search boxes) dropped input or caused keyboard dismissal. Explicit user show requests are now strictly respected.

🛠️ Improvements & Enhancements

• Bluetooth Keypress Audio Interception: Fixed an issue where custom sound pack audio tracks interrupted car stereos and Bluetooth headsets by triggering AVRCP "Now Playing" playback sessions. LeanType now automatically falls back to native system UI click effects on connected Bluetooth A2DP devices, with an optional user toggle (Settings → Plugins → Keypress Audio → Play custom sounds over Bluetooth).
• Floating Popup Keys & Preview Clamping: Corrected horizontal bounds calculation for key preview popups to prevent screen edge overflow in floating mode, and aligned popup rows strictly to parent key space coordinates.
• Stray Navigation Bar Artifact Suppression: Fixed an edge-case where a transparent navigation bar artifact could linger during floating mode transitions.
• Pinned Selection State Fix: Fixed an issue where the pinned text selection mode toggle in the suggestion strip did not reflect its active state properly.
• Theme Contrast & Auto-Reload: Improved high-contrast color evaluation for toolbar key icons and enhanced automatic reloading when the system switches between dark and light themes.
