It should be a easy enough feature to implement. Would save me a bit of work.
I tried a couple of plugins from KingSparta, but they were mostly for download and uploading cover art from the tags inside of the tracks. Helps me very little in this case.
I'll just have to leave my library as it is, and update the cover art tag from the folder.jpg files and tracks that i import.
Let's hope the "Quick find in file / cover art directory" does the trick.
