I just checked into our SVN some skin revisions that will improve a couple of things on MDC, although they won’t work until we upgrade to Lyons, hopefully in April.
One of the revisions will improve our diff displays, removing some extra stuff we don’t need, leaving just the new side-by-side view of the changes.
The other big change is that I’ve moved the “Talk page” link out of the More options menu into the main toolbar, and when you’re looking at the talk page, it turns into a link back to the original article. This not only improves discoverability of the talk pages, but makes it easier to get out of them once you’re there.
We should now be in good shape, skin-wise, for the upgrade when the time comes.
