I find myself going to discogs frequently to confirm meta-data or get album art. It would be nice if the ripper included a button to launch a search in the default web browser for the disc on discogs.

I still think that ideally discogs should be used as part of perfectmeta (even if that requires 2 calculations of perfectmeta, the results of the first used to search discogs and the second using the discogs results), but if this is not planned then this would be a reasonable backup.
