"AlphaBlack Control" Widget

v10 introduced an accompanying widget to easily change the theme's accent color, panel opacity, or change the taskbar to look a bit more like Windows 10.

You can download the widget here, or install it via the GUI:

1. Right click the Panel > Add Widgets
2. Get New Widgets > Download
3. Search for "AlphaBlack Control" and install it.

After installing, the widget should appear in your system tray. If you lock your widgets, it will hide in the system tray popup.
