However, if the pause button is clicked while playing the scene, all the keyframe controls are deactivated so I can't set or move a reference keyframe. If the stop button is clicked the controls remain active, but the location slider "rewinds". (I've used a pencil against the screen to remember where the slider was, but besides being awkward, it's not that accurate and leaves pencil marks. In one clip, it ended up looking like my dog had grown a mustache.)
I'd like to see one (or both) of the following:
1) Best: Leave the keyframe controls active on pause.
2) Usable: Don't reset the time locus slider on stop (which would require a "rewind" button to be added - seems unnecessary.)
By the way, being new here, I'm unsure where requests for enhancements and bug reports should go.
