Steps to reproduce the behavior:

1. Go to the Marketplace for Spicetify > Themes
2. Install Matte/restart Spotify

Expected behavior
A layout that will spread the main window across the whole screen.

more info: I resized the window to as small as Spotify would let it go, with some interesting results:

Here's comparisons of the pixel widths of various visible elements between the different views, in case it's helpful for CSS troubleshooting. Everything's extremely estimated, and apologies for my crummy annotation lol:
