Instead of sorting in the right panel by disk color (changed, unchanged), it would be useful to implement a counter of changed albums after each music catalog load (about once a month, waiting for new, updated tags).

This is helpful when there are a lot of files, because it is difficult to track down a few or a dozen changed albums.

For example, a button "Save only changed files" could be introduced.
