Is it possible to have something in the middle of a pie menu? For example I have put all the modes (object mode/edit mode/vertex paint etc) in a pie menu but want to have pressing tab quickly without moving the mouse to toggle between current mode and edit mode.
When pies were first released, they said they were working on a method to have quick click do one action, and long press bring up pie menu. That way you could have two actions mapped to one key. Not sure if they implemented that (checked release logs and manual and found nothing…)
