Great product - thanks for creating it!
My collection is missing a lot of album art. I am using Perfect Tunes from dBpoweramp to locate the art, which it does very well. It locates an album image and places it in the folder associated with the album, and also associated the image with each of the tracks.
The problem is that Audirvana only associates the image with the album after a Sync - and syncing my whole library takes a long time. It would be great if there was a little button I could click on when viewing the album meta info to just re-sync that album folder.
