"Maybe it is my old-school HTML upbringing, but it does not feel right to throw other things in the mix. List items are the children of lists."

You sound surprised, Justin, that WordPress would ever produce duff HTML code, even though you're the author of a handy plugin that corrected Gallery output!

By the way; does anyone else write and/or do template work on a 13.3" screen, or is everyone using 21"-plus? I often feel a bit hemmed in (I have the right-hand toolbar open all of the time) and usually have to scroll down modals and pop-ups to find the option I'm looking for. Columns tend to be difficult with less space to work in. Just wondering.
