Hello. Installed a soundcard and mp3blaster yesterday. Mp3blaster is great but I think it lacks a media library.
A media library holds all the mp3's to be easily selected to the playlist. I don't know if this is common in Unix but on Windows this is somewhat the default nowadays. Check out recent Winamp or MusicMatch Jukebox to see what I mean. The media library makes it easier to manage collections of hundreds / thousands of songs.
Another suggestion: Change places with "now playing" and Global playback, it would make much more sense.
I'll post both of these as trackers as well.
Not speaking for the devs, and just speaking as a *nix user: Media libs are usually in the format of a system heirarchy, which, if properly done, is just as good as any library you'll find on any good mp3 player.
