This can make editing/fixing a VA release with disambig artists quite hard.
Use case 1: Fixing some track titles on a VA release you are perhaps not overly familiar with, via track parser.
You use release editor's parser to paste correct titles/times from some other source - the release editor will then force you to re-confirm correct artist names.
What you want to do is just use current artists, but the system needs you to confirm them. If you're not familiar with the release you may not know which is the correct one OTOH, and there's nowhere easy for you to see which artist is /currently/ being used to just select that one since
Use Case 2: Spotting at a glance incorrectly assigned artists on a VA release to fix them in the editor
Often I come across VA releases with many incorrectly assigned artists. First issue is that currently it's hard to see at a glance mistakes on release viewer. Second issue is that normally I'd intend to change them in release editor, perhaps via the advanced tracklist editor, but you can't see which disambigged artist the track is currently assigned to there either.
If the issue here is screen real-estate, perhaps they could at least appear in the mouseover with the sort name, or in a small java-script mouseover overlay as you run down the artists list.
