I just want to give props to the team who made the changes to WordPress...
I pretty much love them. It's the little things, like the list of files in Design > Theme Editor, whoo-hoo!
The only thing I've found that I don't like is that you can't move the order of the collapsible funtions in the write and manage admin pages -- it's a pita to have to scroll up and down after each entry of a custom field, for example. It should either not pop back up to the top or you should be able to arrange those functions so that the ones you use are closest to the top (page parent, page template, etc)
But overall... joy!
