It's great to try new formats, but the experience is completely broken on my now-slightly-aging Windows laptop. I wish web developer/designers would test their pages on regular hardware instead of 27" iMacs or rMPB... The scrolling is horribly lagging, and the gifs/videos are all black: http://prntscr.com/1gq4he http://prntscr.com/1gq5b6
But it'd be nice to be able to say, "Yes, this version in chrome is what I want it to look like," and you get back scores that determine how "close" the other versions are to the version you selected as your reference (0-100%?).
Seems like one could achieve this with some sort of pixel diff algorithm.
