[Desktop] Make desktop version compatible with 21:9 Ultrawide

[joeyhockey]

Y'all should either make it so when you're viewing Spotify on an ultrawide monitor (21:9 Aspect ratio) the main content you're looking at is either centered on the screen or is how it currently aligned (left justified) but the content takes up the full screen rather than stopping 3/4 of the way across the screen. IMO It should fill the whole screen between your playlists (far left) and what your friends are listening to (far right). Obviously this is a first world problem and I there are probably more pressing things, but I use Spotify every day and this drives me crazy. Thanks!
