Final Cut Pro – How to Reset/Remove All Buttons in a Button Bar
Its easy, if you know where to click.
Removing all the buttons from a single window can be done with a single click of the mouse.
Control-click any button.
From the pop-up menu, select either Remove > All, or Remove > Restore Default, depending upon which window you are in.
Extra credit: There’s only one window which provides the All/Restore Default as the choice. Which is it?
