It would be cool to have multi-screen tablet app.
So example: I could 2 Android tablets, run MS X32 on both of them, but control layers/layouts from single on both of them. In such case, I could have layer 1-32 spread across both when 1st tablet would contain 1-16 channels, and 2nd tablet would contain 17-32 channels.
Generally, some kind of communication between Mixing Station apps between each other. I'm even willing to pay extra in-app purchase for such feature.
(while I chose, it's for XM32, it could be just general)
