Issue title: Better mobile view
 Issue body: I would love to use this app as a daily driver for Spotify on my mobile device. I'm wondering if we're able to make the view take up the entire screenspace on a mobile device and pin the scroll wheel closer to the bottom of the screen.

 Comment 0: Hey @crutchcorn, totally agree mobile could be better! I did some experimentation a while ago on what looks best for mobile devices, and as you can see from the screenshot, the bigger the viewport is the stranger the layout gets as it stretches. My opinion at the time was that it was better to just limit the height rather than stretch it out, but I'm open to other opinions as well. Thanks!

 Comment 1: For sure, I feel that. 

I personally don't mind that stretching, even tho it's certainly not in the design spirit of the original

I guess my thing is that I'd rather have it aligned to the bottom of the screen (rather than the top, where it seems to align on mobile right now), as it would allow me to more easily access the scroll wheel 
 Comment 2: I like that idea! I'll file a quick fix to align it to the bottom and then work on figuring out a better utilization of the full screen. Thanks for the suggestion!
