I’m using prototype to do the “drawers” now.

34 reasons:

• No need to show them on page load since, I think, the links to the drawers are noticable enough.
• 3 less javascript files your browser has to download (24k)
• Opera never played nice (still a few issues but I just can’t help it).
• The subpages are now shown automatically on all the pages.

Next up IE but I might as well wait until K2b3.
