Create (update) XUL cheat sheet
If we prepare (updated) XUL cheet sheet, it will be great help for Mozilla developers, especially for beginner developers I believe.

And, if we also create printable cheat sheet, it must be helpful too especially for on-site workshops.
Thanks for the suggestion. I moved this post to the new "Dev Doc Priorities" forum, which is where we are going to be gathering ideas and votes on where to focus documentation efforts.
