It would be nice to have a 'lock' on a per screen basis so that you can't accidentally change it's scale or position.
We do a lot of scribes that rely on the scenes being registered in position with each other, both in scale, and position. It would be nice to 'lock' those scenes so that they don't accidentally get out of registration.
In addition, having the numbers for scale, position, and rotation available would help the cause. I appreciate trying to keep the interface as 'clean' as possible, so maybe having an additional toggle to bring up this info when needed.
Both of these would help us greatly!
