My Codex todo list, at least the portion I've put a little planning into (mainly template tag work).

Template Tags :

• Drop invalid tags, specifically *_unicode().
• Organize Template Tags groups a little more logically.
  • Link & Permalink combined?
  • RSS group?

Individual tag pages :

• Tag pages have "complete" content.
• Tag pages have example(s).
• Further wikification, links to Glossary entries.
• Style standardization for tag references.
• Colorize php tagging on usage: %%% (don't use for examples?)
• Verify tag parameter names.
• Verify tag parameter functionality. (nearly done)
• Insert argument type (i.e. string, integer, boolean).

Installing Multiple Blogs :

• Rework from old wiki - first draft completed.

How to Pass Tag Parameters :

• Fill out descriptions. (Turned into major rewrite!)

Anatomy of a Template Tag : - Moved as sub-document to Template_Tags.

• New document - working on first draft.

The Loop :

• Insert help/guidance on use.
