The new list extension MS announced looks pretty easy to deal with - if I wasn't going to be busy with Smalltalk Solutions next week, I'd have an update with support ready in a day or two. I'll plug away at it in spare moments, and should have something out before the end of the week after StS. The cool thing is that Bf already has all the sorting/filtering capabilities this extension requires; all I need to do is capture the meta-data and expose it.
