The drop down menus should be simpler and more aesthetically pleasing. Perhaps use a simple arrow without the black tab. Then when we click the arrow the same layout you have on the menu can be shown but with a slightly transparent background.
Also, allow us to change the color of the toggle for groups - this way we can organize it even further by color coding it.
Otherwise, great extension. This is the only one that allows multiple groups.
