my scenario: I've configured a global touchbar with some volume and media keys which should appear in every app.
Now, if I am in a specific app, I would like to show a different touchbar layout, but only on hold of a modifier (similar feature like holding the fn-key to show the f-keys..)
So as a example: when I'm in Photoshop, I want to reveal some app-specific buttons, only when holding for example the control-button.
Is there any way to do it in BTT? I know I can configure separate touchbar-layouts for specific apps, but they're shown automatically on app-switch.
Would be very nice to get some help here!
