Of the problems mentioned at: http://article.gmane.org/gmane.comp.emulators.wine.devel/41377
your idea provides a solution for 1, 2, 3 and 4. That's of course really nice. It doesn't have a solution for 7, which is something I think will be missed.
And 5, and 6, and 8.
And at the bottom of the 'subscribe' page for Google groups is a nifty link that reads: New! Get email alerts of messages containing specific keywords.
So I think that 7 is covered as well; you can also click on the little star to watch a particular topic via the web page.
So the only one not covered imho is 9, the 'sticky' feature.
But is it good enough? It's rather inflexible since we can't change anything if we don't like it..
Perfect is the enemy of good (or something like that, I forget the exact quote :-/).
Cheers,
Jeremy
