I would like that as well and agree with @Slak_Jaw that all of the panels should be MIDI-mappable. I think djay on iOS currently does a rather poor job adjusting to a connected controller because you still have to use the screen for many things like changing panels.
I have also created a similar topic that goes in the general direction of making djay more of an enhancement of the Controller: Give us a viewing mode made for controllers (like „Pro“ mode on macOS)
