hi there
I recently discovered MB. Congrats, great job.
I had a library with 40k sound files (mp3s, flac etc). These days I'm trying to build a new media library with music videos, ad clips, podcasts, movies (mp4, mkv, webm mostly).
I don't like itunes for many reasons and i try to use MB as an alternative.
The support for webm files natively (just like VLC) i think is essential.
Also, tag writing support for video files (just like Mp3Tag or TagScanner).
Congrats again, keep up the good work!
