I'm posting this to wikipedia-l rather than wikitech-l, so nobody can accuse me of secret implement-and-install action again ;-)
I have installed another version of the "Enhanced Recent Changes" at http://test.wikipedia.org It features a better alignment of entries, and a "user summary", among other things. The look might be a little more "technical", though.
Great! A lot better than the previous version. The user summary is exactly what was missing.
