It could be help if we had keyboard shortcuts (and Midi mappings) to switch the UI layouts like:
Cntrl+Opt+Cmd + 1 for 1 deck,
Cntrl+Opt+Cmd + 2 for 2 decks,
Cntrl+Opt+Cmd + 3 for 3/4 decks
Cntrl+Opt+Cmd + 4 for Automix
Cntrl+Opt+Cmd + 5 for Video
Thanks for the suggestion! Good idea. I have forwarded this to the dev team for consideration.
