Just to add a few things

 As I put in the first commit: Updated GUI to be more user friendly / eye candy, added changeable background in settings. Fixed a few issues that could cause a crash / not able to queue. Add whatever changes you like I guess. Side note - Forgot to remove all the things that I did just to get the warning count down, and can't figure out how to replace a commit.

EDIT:  Side note, first push ever - Apologies if it's awful.

EDIT 2: Yup it's awful, oh well, no idea how github works and can't pull back my commits, my bad. (thought I could change a pull - found out I can't)
You don't have to comment things out - this is the big profit of a version control with history. 
You are able to revert everything at anytime.
It's 100% safe to remove things
