So I understand that Motion 4 is in BETA now, and I'm using 3 as I've just got the machine up and running. That said, I was hoping to use Motion with a touch screen interface only and in my 1 hour of playing with it have found that it has a few issues that prevents that goal.
When in Full screen mode (FSM), it beeps at you if you try to load a file. You must exit FSM, find the file, then reopen FSM. In my opinion, it should open a file selection box without exiting (or automatically exit FSM to allow you to select the file and then reopen in FSM)
When trying to type to change the settings, it does not open an onscreen keyboard to allow input from touchscreen.
I hope these two issues are addressed in CM4!
