It is a pain, but there is the ability to take a "snapshot" which show up transparent over next frame. Oshiro had a recent video showing it in the last week or so. You hit a function key, move forward, do new frame, snapshot, move forward etc
I agree it's very annoying... for now the only option is do do a snapshot while disarmed. It would be great if there was a hot key to switch between modes when it's armed - to view either the default position or the current position.
