Disable/hide visual borders when hovered over, atleast in full screen mode. It makes the UI look pretty untidy.
I think this would be a fantastic option to have. As was mentioned below, sometimes it does not make sense to have the border on hover e.g. when a shape is inserted. Other examples would be on a slicer, I only want to select the buttons, I have no need for a box allowing me to turn on Focus Mode. Implementing this would make the final end product to the user even more polished
