I hope putting a circle on your screen brings you as much happiness as it brings me... shut up that's not lame.
Add pie menus to any application. Similar to Blender pie menus or Maya marking menus.
In order to activate a pie menu with a pen button, go into your pen software and set a key to send '4th click / Forward' or '5th Click / Back'. You may use any other key, but other keys may not send their 'key-up' signal when the pen button is released. You can then set the Pie menu key to respond to '4th click / Forward' or '5th Click / Back' in the 'Special Keys' menu.
Most bluetooth controllers can have their buttons assigned to a keystroke in their software, however most do not send their 'key-up' signal when their button is released. To handle this, use the 'Hover over all selections' launch mode. The pie menu will stay open after the button is pressed, and selections can be hovered over to be selected.
