Changelog

This page tracks notable LinguaX app release notes, including input switching, mouse enhancement, smooth scrolling, and gesture updates.

2025.12.4861

Summary: A reliability-focused release for Logitech Bluetooth mice — buttons recover faster and more dependably after an Easy-Switch hand-off or waking from sleep — plus on-screen action feedback and expanded modifier-hold.

New Features

• Action feedback: a small marker briefly appears at the bottom-center of the screen when a mapped keyboard/mouse action fires, so you can tell it triggered (toggle off in Settings).
• Expanded Modifier Hold: ⌘ / ⌃ / ⇧ / ⌥ now all support "hold to apply, release to restore" (previously Fn only).
• Cleaner input-source rules: App / Web rules now use a clearer segmented switch.

Improvements

• Faster Bluetooth recovery: Logitech Bluetooth mice restore the scroll-mode key, side buttons and more faster and more reliably after an Easy-Switch hand-off or waking from sleep.
• DPI persists: Bluetooth mouse DPI now keeps your set value after restart / wake instead of falling back to default.
• No first-press delay: fixed a delay on the first button press after the mouse had been idle for a while.
• Steadier connection: overall improvements to Bluetooth connection stability and power use.

Fixes

• Fixed occasional unexpected quits when using Logitech Bluetooth mice — the Bluetooth layer was reworked from the ground up to be more stable.
• Fixed a rare startup crash — a database load failure now recovers safely instead of quitting the app.

2025.12.4850

Summary: Adjust your Logitech mouse's DPI and scroll-wheel mode right inside the app — no official driver needed — plus run Apple Shortcuts from mouse buttons and keyboard mappings, and a new option to hide the menu bar icon.

New Features

• Adjust mouse DPI: set your Logitech mouse pointer speed (DPI) with a slider directly in the app, over both USB and Bluetooth, without installing the official driver.
• Toggle scroll-wheel mode: a new "Toggle Scroll Wheel Mode" action switches between free-spin and ratchet scrolling in one click (Logitech SmartShift).
• Run Apple Shortcuts: both mouse buttons and keyboard mappings can now run your Apple Shortcuts.
• Hide the menu bar icon: an option in Settings hides the top menu bar icon for a cleaner look; reopening the app restores it.

Improvements

• Tidied up the action menu: "Open Application" now lives under the "Apps & Windows" submenu, and Shortcuts sits on its own at the end, making actions easier to find.
• More reliable Bluetooth capability detection: DPI and scroll-wheel probing now retries and resets on failure for steadier reads on Bluetooth mice.

Fixes

• Fixed Logitech M720 and similar devices being ignored — composite Bluetooth devices that declare both mouse and keyboard are now recognized correctly.
• Fixed already-bound combos getting disabled during recording — keyboard triggers are no longer permanently turned off while recording a mouse shortcut.
• Fixed flicker and stutter in the Shortcuts picker for a smoother, more stable list.
• Fixed several scroll-wheel mode toggle glitches around rapid double-clicks and reconnects.

2025.12.4845

Summary: A big upgrade to mouse-button keyboard shortcuts — record richer combos (including ones that were previously impossible), plus a new Open Application action and Logitech Lift support.

New Features

• Mouse buttons can now record Fn-based combos, such as Fn + Space.
• Mouse buttons can be set to send a single modifier key (like Fn) with a quick press.
• Added an "Open Application" action to launch a chosen app from a mouse button.
• Added Logitech Lift support.

Improvements

• You can now record shortcuts that are already in use. Even if a combo such as ⌘⇧V is already bound to another shortcut, recording it for a mouse button now works correctly instead of capturing only the modifiers.
• Clearer shortcut display: a standalone modifier now shows as an icon plus label.
• Redesigned the device Diagnostics Center with a cleaner layout and one-tap diagnostics export, making device issues easier to investigate and report.

Fixes

• Fixed the battery indicator flickering between green and red on some Logitech devices.
• Fixed the Stage Manager action not running.
• Removed non-functional checkmarks from some menu items to avoid confusion.
• Fixed repeated clicks opening multiple app-picker panels.

2025.12.4834

Summary: New side-button swipe and modifier-hold gestures, fluid Space switching, and more reliable licensing across system upgrades and iCloud changes.

New Features

• Added swipe trigger modes for side-button drags, so dragging a side button up/down/left/right can trigger different actions, with a clear on-screen mode indicator.
• Added a modifier-hold mouse gesture that triggers an action while a modifier is held — ideal for push-to-talk voice input tools like Typeless, where the action stops as soon as you release.
• Added fluid, trackpad-like Space switching for smoother desktop transitions with your mouse.

Improvements

• Redesigned device licensing so activation stays valid after macOS upgrades, iCloud account changes, or device migration.
• Improved horizontal scrolling reverse and compatibility for more consistent behavior across apps.
• The running-apps list now refreshes automatically when apps launch or quit, making per-app setup easier.
• Optimized settings UI rendering for smoother scrolling in the app scope switcher.

Fixes

• Fixed cases where smooth scrolling could stop working.
• Fixed app-specific overrides that could swallow events in other apps.
• Fixed horizontal-scroll button ID parsing in app override configurations.

2025.12.4816

Summary: Per-app smooth scrolling, steadier mouse gestures, and improved side-button/device recognition.

New Features

• Added per-app smooth scrolling controls so each app can have a scrolling behavior that fits how you use it.
• Added Logitech G502 X recognition for more accurate model detection and setup.

Improvements

• Improved mouse gesture timing so drag and swipe actions feel more predictable during daily use.
• Improved automatic side-button mapping for recognized mice, reducing manual setup after detection.
• Refined mouse enhancement controls and improved About page icon appearance in dark mode.

Fixes

• Fixed thumb-button and wheel-tilt setup issues affecting some mouse models, including MX Master 3.
• Fixed smooth scrolling edge cases so scroll distance remains more natural when smoothing is disabled or bypassed.
• Fixed gesture coordination issues that could make complex mouse actions trigger inconsistently.

2025.12.4811

Summary: Clearer media-control organization, broader key-trigger coverage, and stronger mouse compatibility.

• Improved localization for wheel tilt left/right labels to make direction semantics clearer in multilingual UI.

2025.12.4803

Summary: Stability-focused update for smoother long-running use and a better reopen experience.

Improvements

• Improved long-session stability for smoother daily use.
• Improved responsiveness during frequent mouse interactions.
• Improved overall runtime consistency for extended sessions.

Fixes

• Tuned double-click detection to align with system settings for more natural trigger behavior.
• Bluetooth devices now recover automatically after sleep/wake without requiring manual reconnection.
• Reduced CPU usage by optimizing mouse-movement event handling in the background.

Fixes

New Features

• Added full SM thumb-button gesture support with stronger mapping coverage for click, double-click, long-press, and swipe actions.
• Added per-device pointer speed persistence, so each mouse keeps its own speed profile.
• Added immediate pointer speed application through a lower-level system path, without app restart.

Improvements
