[Feature request]Live-preview floating button while adjusting size/opacity sliders

Current behavior
On the Settings screen, the Widget Preview animates in real time as I drag the Button size and Button opacity sliders, but the actual floating overlay button on screen only updates after I lift my finger from the slider.

Expected behavior
The real floating overlay should resize and fade in real time while the slider is being dragged, exactly like the preview does. That way you can visually pick a size/opacity that fits your screen without a lift-check-adjust-lift-check loop.

Why
The current 'commit on release' flow is redundant — the preview already shows real-time changes, so having the live overlay lag behind creates a two-step feedback loop for a purely visual setting. Making both update together removes the friction and makes tuning the button feel direct.

Device
Android 16, tested with the current release from Play Store.

Start at the Android Settings screen handling the Button size and Button opacity sliders, then trace how the Widget Preview receives changes and how the floating overlay is updated. The work is done when the real overlay resizes and fades continuously during dragging, matching the preview without waiting for slider release.
