Floating window replacing touch-bar, sort of.

Hi!
awaiting my new macbook because i destroyed my 2019 macbook, i'm looking to replace my touchbar setup using BTT with rekordbox. I was stoked to see the wonderful things you've made for Notch Bar. So, I am already a happy camper. But it got me thinking how awesome it would be if I could press eg CMD, while having Rekordbox active and have BTT reveil a Window (Like the CMD-Tab function in Mac OS). For me it would reveil 8 icons of specific playlists and holding down CMD and clicking these icons would trigger a shortcut, sending me to the corresponding playlist in Rekordbox. My touchbar was setup to do that but this would be nice as well. I could use notch bar for these functions but a larger display for the playlist icons would be a huge plus.
