I’m currently working on updating some help tabs for WordPress 3.1, about to go into Beta. See Trac Ticket #15346 (Contextual Help Tabs Cleanup) with patches I’ve submitted for individual dashboard screens.
For background on WordPress help tabs:
- Codex article on Adding Contextual Help
- More on the code behind it (see especially the update in the comments of May 12)
- Lorelle VanFossen’s thoughts, especially on adding contextual help tabs generated by plugins
