I'm not sure if this is an official feature of Moho, or if I have stumbled upon a hidden feature, but it is possible to modify your Moho file while preview is playing. Moho records the changes neatly into keys of the appropriate animation channels. I think it can be useful for quick and dirty animation with layers and camera movements.
I temporarily modified the frame speed to 4 fps, so I could move the layers and control the camera more easily in slo-mo.
Here are the files:
live_edit.moho (40 KB)
live_edit.mov (Sorenson Video 3 codec, 700 KB)
Have fun experimenting!
