in addition to full screen and global zoom functions, it would be great to lock the scope of astropad to a specific window and possibly toggle between multiple windows.
this way if there is a window I always want to see on the ipad (some palette or canvas) I can lock the view to it, then even if I move it around on the screen, astropad follows the window
Think of how screenshots work
Full Screen = apple-shift-3 ; This the same as the fullscreen zoom
some region = apple-shift-4 ; This is the same as the “edit” function in the floating window on the mac
specific window = apple-shift-4 then spacebar - this would lock the astropads field of view to the chosen window and all zooming would be limited to those boundaries
