Allow maximizing the window

[Ecnassianer]

My music library has a bunch of similar titles of songs, so I want to see the whole album name in the queue. When I show the album name, the queue window is too narrow and so everything gets shortened into "...". I would love to be able to maximize the window so it can use my full screen space to display that text. It would cover my use case completely.

There's a much needed UI rewrite that needs to be done. I'll need to spend a lot of time thinking about how to go about it and when I'll have the time to do it.
