Our developers are happy to hear you’re all big picture kind of people. Bluescape is excellent for being able to get a birds-eye view.
About video replay, this is an existing feature requested, and your feedback has re-sparked discussion. 
I’ll leave it in the capable hands of our developers and follow up should we have good news for you in the future.
Lastly, I tried to recreate the image behaviors you were describing in a workspace of my own. Can you please confirm whether my resizing of the image on the right (see below) is what you are experiencing?
Thank you, @alyssa.
