Widget Group Button

This plug-in adds a group button widget, which is the same as a
normal button. This group button adds a selected state and
corresponding events. The advantage of the group button is that
when this button is selected, a selected event is triggered, and
other group buttons in the same group as this button are
unselected.

Modify the workflow, make sure to cancel the selection first and
then perform the new selection. Removing the font files in the
original plug-in reduced the plug-in size from 30M to 150K.
