I thought it might be helpful; I tried the following popular plugins with the latest release of bbPress and they seem to work perfectly:
- bb-smilies
- bbcode-buttons
- mini-track
- my-views
- post-count-plus (with some minor changes)
- support-forum
- bb-reputation (to some extent)
- bb-signatures
- bb-topic-views
- bbcode-lite
- hidden-forums
- report-post
- unread-posts
what is missing most is the working plugin for quotes...
