This definitely looks like a convenient feature although it's something I would ideally have added right into Chrome. It is not really related to the streaming/syncing responsibilities of the app. Any site which plays video could benefit from this non-window-resize-fullscreen feature. Another option could be creating two extensions: one for the video syncing, and one for the non-window-resize-fullscreen. That way if the latter gets rejected it wouldn't affect the former. Note I'm sure some people definitely prefer the desktop app approach and I wish you all the best getting the approvals you need for that. This is just how I would prefer to use it.
