Some features that would be cool to see in the GUI tool are: an option to enable blur on taskbar (instead of making the cmd file and vbs file on startup), option to install unsigned themes dlls, fix the ability to set custom glass colors (in win10 10586 you can't set custom colors in the gui tool, only in legacy personalization colors settings), and the option to match title bar colors to the taskbar (currently this has to be done in legacy colors settings by lowering brightness.) And also, if possible, a way to change the glass colors of start, action center, etc. so that everything matches. Stray observation: when setting a custom color with aerogui tool, the one-pixel barrier and taskbar do change to the custom color, but the title bars, start, action center, etc. don't.
