No need to apologize - feedback is good!
So nothing is being lost - when scrolled to the top you should see the full “controls” area like you do now. (I see that my mockup is confusing because it’s scrolled to the top…I’ll fix that fixed). Only when scrolled down would the controls collapse. I’m not against adding more info to the collapsed header, we’d just have to ensure that it all fits.
Mobile is a whole different issue. We show a desktop-sized modal that requires scrolling sideways to see everything. I’m all for improving it but that may need a topic of its own - it’s not pretty right now.
