-sigsegv sometimes when: starting with 1 mp3 on commandline, stopping ([]),
 [hitting play], starting playlist (F9), quit
-'next group' knop
-save shuffle mode for main group, and playback mode for entire group in
 playlist
-change cd-style keys to have logical mappings on the numeric keypad
-skip certain directories (e.g. '.resources' and some more..)


scrollWin class: Use a global variable to determine for each function if
                 the window needs to be refreshed. This is much more
								 userfriendly for the end user of this class!
mp3blaster: 
Basic features:
-move all selected files in filemanager to current dir (m) (!)
-import/export playlist (compatible met o.a. winamp) (fixed? might work :))
-fix warning()
-sort order of files in groups!
-rename global playmodes to make sense 
[-missing playmodes (mp3win->beingPlayed() function?)]
-clear mpeg-info when songplay's finished.
-rename group->getPlayedmode() to group->randomOrder()
-lock on group->playing/played (for deletion) + lock on group access...
-split up playmode PLAY_GROUP in 'play current group but not its subgroups' and
 'play current group including subgroups'
-help in scrollwin! (separate program mode + scrollWin obj)
-read/write playlist +save tmp.playlist to continue it later. (partly done)
-scrollable input in popup_win ?

Enhanced functionality:
-'skip to next mp3 and delete this one from list'
-pulldown menus instead of space-consuming help window!
-filesize in filemanager f/each file:
 -<10Kb: 9999 B, < 10M: 9999 KB, < 10G: 9999 MB, 9999 GB

DONE:
-configurable keys
-kleuren groups
-next song: clear line before drawing a new song in it
-crashes on null files.
-playmode change from group-mode to any other: BROKEN (fix: function
 reset_playlist) - can't change playmode during play anymore
-next song: update it when :user deletes mp3/group, changes playlist mode,stops
            playlist, goes back one song, ..
