As far as functionality, I don't care either way with the menus. I don't necessarily see the need for change though. However, I am having a boatload of issues on IE7, which I have to use for the majority of my WP work (not by choice). Opened a variety of tickets centred around IE7, one involving the uploader that was successfully closed/fixed. http://core.trac.wordpress.org/ticket/18924 Is the one I have for the flyouts that was closed/fixed, however, the fix doesn't work. Basically the menus on IE7 are unusable. The tuck behind everything on the admin page.
