• Link parsers
• Caches
  • Add suppor for caching macro block generation
  • Add caching of "static" blocks
• More syntax support
• Implement all missing macros (all the radeox macros we had)
• Modify document link saving (no need for rendering, just parsing)
• Find a way to move all old rendering code to a separate package so that it can be easily removed later and so that we have some clean code left (if possible)
• Make the XHTML parser fully work (lots of issues, see http://code.google.com/p/wikimodel/issues/)
• Question: how do we support automatic inline editing?
  • Answer: wait for JV's modification. He'll remove the need for includeForm.
• Check for view rights in the include macro
• Groovy refactoring and new grooy module/components
• Add translation support in include macro
• TOC macro:
  • add internal link targeting sections (temporary solution already committed waiting for LinkBlock to support children blocks as label)
• Add support for tables
• Add support for verbatim blocks
• Add support for definition lists
• Add support for quotations
• Add support for parametrized elements (stlying)
  • Parametrized paragraphs
  • Parametrized Lists (not working for nested lists)
  • Parametrized words
  • Parametrized sections

... and a lot more I'm sure (this list should be edited as we progress)
