[Desktop][Mini-player] True mini-player with queue (restrict album art resize)

[JoaoMalhao]

Thanks for implementing the mini-player. However, to be able to see the queue, the smallest size window covers almost half of height of my screen. The album art takes up about 40% of the vertical span, the song title and artist another 20%, and the smallest size shows a queue 7 songs deep (img.2).

Static album art really is of subjective value, specially when it takes up screen space on a window that is always on top.

My idea is to have the option to constrain the album art to the smallest size (same as with the mini-player fully collapsed vertically - img.1) so that the queue would start to show when expanding the window vertically. 

This way if you only want to see the next song on the queue the mini-player remains truly mini (img.3) and if you want to see more of the queue you have the option to keep making the window taller, as you already do.

An additional option in the mini-player settings like "Compact view" could be added, for example.

The horizontal behaviour should stay the same, it's already great.

I have attached a couple of images illustrating demonstrating:

1. Smallest possible current size;

2. Smallest possible current size with queue;

3. An edit of what the smallest mini-player with queue could be.
