#1246 Improvements to Media Library

[Desere Hidovsky]

Hi! Thank you for maintaining this wonderful piece of software for so long.

One feature which I always dearly missed was a Media Library with good filtering options and integrations with skinned mode panels. Well, I've made it.

I'm using a Git clone because I can't/don't use SVN (sorry) but I hope you might be able to get some ideas from this project nonetheless, it's hosted on Github at https://github.com/desertmilk/qmmp-with-media-library
