Simple we need to be able to
Scrub the timeline in the video editor
Also need to be able to pause when playing preview
Finally with both options being able to create a key and/or a view(camera, scene - pick your poison based on the software you're using) at that scrubbed or pause location.
Think of the possibilities to be able to create an in between key that's actually based on where you are helping smoothing out animation or even bettering your orbit...
