I’m new to bbpress. In fact I’m on my first installation and I like to see the development.
I think the way the systems are now is good. They should remain separated. In the same time, it makes sence to develop exactly two plugins for the integration: one for WordPress and one for BBPress. The existence of many plugins for the “integration” (SSO, funcational/feature, admin) makes it confusing.
The most important thing missing is API documentation and Theme-Zoo.
Functional features I miss would be:
– wigdet support
– appearance management / editor (see WP)
