I think having multiple profiles of shortcuts for different apps would benefit users a lot. Personally, I'm using Astropad with Photoshop and blender, and it would be super helpful if I could have a profile of shortcuts for Photoshop and another one for blender instead of reconfiguring the shortcuts every time I switch apps. For example, on Photoshop I'd assign profile one with Brush+, Brush-, Brush, Eraser, etc and on Bkender I'd assign a different profile with the shortcuts Object Mode, Edit Mode, Top view, Side view and so on. I don't know if this is even possible but it's a feature I'd love to use, and since the shortcuts are saved on the computer app and not the iPad, there wouldn't really be any performance impact (would it?).
