The fix is only 3 small changes - but when those are done, what more needs doing? It looks fine as-is IMO.
Anyway, I'll certainly be able to do those; how do you want them? The whole file - in a pastebin, say - or a short description of the exact changes to make, or are you familiar with diff/patch? You've edited the main monobook file directly, so there's no mediawiki: page to edit/put stuff on the talk page of.
After that, Iunno. Maybe I could do something. I do have lots of projects going on ATM, though.
