Opacity Controller v2.0
A major update — Opacity Controller now has a full UI window alongside the existing tray + hotkey experience.
What's new
Full UI window
Select any open window from a dropdown, drag a live opacity slider, and use one-click presets (Ghost 20%, Half 50%, Focus 70%, Solid 100%). Open with python main.py --ui or double-click the future .exe.
Multi-window support
Make as many windows transparent at the same time as you want. A scrollable active windows list at the bottom shows every transparent window with its current opacity — restore any of them individually or all at once.
Custom hotkey
Change the default Alt+T shortcut to anything you want from the Settings window.
Opacity nudge
Alt+↑ and Alt+↓ adjust opacity 5% at a time on whichever window is in focus — no need to open the UI.
Auto-start on boot
Toggle from the tray menu or Settings to launch automatically with Windows.
Settings guard
Opening Settings while it is already open flashes the window and plays the Windows alert sound instead of spawning a duplicate.
DPI fix
Text and UI elements are now sharp on all displays including high-DPI screens.
