Big picture mode was completely stagnant, until like stated, they started working on the Deck. The new Big Picture we have is nothing but a Steam Deck UI backport. Hell, for a while it would use Steam Deck’s screen ratio no matter what, meaning you’d get black bars on 16:9 screens.

Don’t get me wrong, I think it’s great they’re finally pushing things again, but they were stagnant for a very long while. Ramming the downvote button in a blind panic doesn’t make that less true :)
