This is the #1 feature I have been looking for. Uploaded videos (mostly YouTube links) take up a huge amount of screen real estate and force the person viewing the thread to scroll too much. I would love a feature that shrunk the video into a pre-defined size in the same fashion that Facebook uses. Anyone?.. :-)
My Youtube embeds are only about 640X385. Hardly a lot of screen space on a standard 1080p monitor. But I agree video sites should offer a variety of sizes. I mean, what does vb 4.1.2 do for the mobile style?
