After recent redesign, the buttons in review queue [No Action Needed] and [I'm Done] look almost the same. I would start competition if you can distinguish which one is disabled on the below image (but I believe the sharp eye of reviewer can find some differences).
Can we get this improved, so the difference is obvious on the first sight?
For comparison example screenshot from superuser makes it much easier:
It is not problem for me, but it might be complicated for new reviewers, since they will not get visual guidance and might get frustrated with non-responsive buttons.
