It’s a really nice tool!
The only problem I had was that I imported a sound library with a few thousand sounds and then decided I don’t want these sounds… I deleted them from the file system but they stayed in the app. It correctly detected them as missing, but to be able to remove them I would have had to delete every single one of the sounds by hand…
Luckily I found the SQLite DB thanks to the comment below. I simply deleted the whole DB and started over. Would be a nice feature to re-sync with the file system and auto-remove missing files.
