I want to have my touch bar change when I have different windows open. When I try this it just overlaps the touch bar I have set. Is there a way to do this?
If you want a Touch Bar that shows up only for YouTube (if I gut you right) the Conditional Activation Groups (can be created using the bottom left plus inside BTT) are helpful. Create a new group with all* condition are true: "App name is --Your Browser--" and "Window name contains Youtube". Then put there all your desired actions.
