WordPress is excellent, as are the wealth of available plugins; there is some functionality I would like to add, however I want to check if the functionality is either planned in 1.3 or already available as a plugin. If not (or even if so), I'm interested in assisting in the feature creation.
Integration of Comments with User Accounts: I'm almost certain this is planned for 1.3, since a
user_id field was added to the comments table. However, this support is not yet implemented in the current CVS (as of the 10th of the July). This would also add a "Registered Users Only" comment mode for posts.
View Level Integration: The view level plugin is excellent, however I think it could be better implemented by adding a field to the post table. The view level filtering could then take place at the SQL query level, which should save computation time.
I apologize if there is a separate forum for 1.3 plans and features (please post a pointer).
