The edit form changes that I mentioned previously: http://lists.openguides.org/mail/openguides-dev/2007-April/001653.html
are now in svn. Basically, there are no longer any tables involved; it's all done with <div>s, which gives you much more flexibility. I'd really appreciate it if those of you with customised edit forms (Boston, OGL, etc) could have a look at it and see if it lets you do what you want to do. The new classes and things are all documented in README.CSS.
If you have any trouble with it, please let me know. I'd quite like to get this released reasonably soon.
