Re: bbPress Admin
Personally, I didn’t like the WP2.5 admin, and I don’t like the current BB1.0 admin.
Furthermore, I don’t think the WP2.7 admin is going to be changed significantly in 2.8 or 2.9.
I think a big mistake was made with WP2.5, and this was realised by the WP devs and replaced by the excellent WP2.7 admin. They now have a good admin and I think they’ll stick with it.
I won’t be using bbPress on a live site anyway until it integrates better with WP and shows signs of being actively developed – looks like this will be soon, due to TalkPress – but additionally, the current admin is a big disincentive for me.
