2 - support for more playlists
3 - playlist: configurable columns
6 - don't quit by closing mainwindow?
7 - more advanced search in library
8 - queueing (MPD feature?)
11 - split library by letters (like Amarok)
12 - icons could use a lot improving
13 - waste less memory (library and playlist are main suspects)
14 - Lyrics - should use only Qt's xml functions and allow user to select lyrics
15 - Get rid of the Settings widget. It's mostly useless -- its functionality
16 should be moved to the plugins themselves
17 - switch to python3? -- waiting for PyQt4/PySide py3 support in Debian
19 - support new MPD features:
23 - review and cleanup everything
24 -- MPD interaction layer -- rewritten completely, should be somewhat fine
27 -- settings widget -- to remove
29 -- plugins architecture
30 -- the plugins themselves
