Semi-regular Warpcast annoyances thread

If you were BDFOWF, what would you have us work on? 

Ideally it's specific and small-ish, i.e. "add video" is not that useful :)

BDFOWF = benevolent dictator for one warpcast feature

I take back my first offering and replace it with this:

I would fix the media support, especially in the realm of cropping of images, thumbnail behaviors, open up the media support for more such as yes, video even, but especially provide signifiers as to why a GIF (or other media?) fails to load in the cast preview..
