Added single-entry settings menu, long-press functions, Global/Independent settings toggle, Scroll range reduction, Partial feature disable. Key5 long-press toggle speed, Key1/3 long-press non-linear acceleration. Added initial volume memory, video switch focus. Volume save debounce, clear settings. Force unmute protection. Fixed volume modifier key support for wheel events. Optimized long-press detection time and Key 1/3 repeat rate.
