I have a late 2013 13" rMBP running Mojave. I just installed BTT. Set a three-finger tap in Mission Control to Quit the App under the cursor. But it doesn't work--the three-finger tap just selects the app under the cursor, just as it would if BTT weren't installed.
Is there some other step I need to be doing to "activate" the gesture, or is this a bug?
input device is MacBook trackpad.
