I like what acelin said, but as long as we don't have too many dang icons. How about we have well-sized and placed icons that are actually nicely-animated menus? We can have the standard menu bar, then this special toolbar, then a multi-bar that changes depending if you're working with text, pictures, objects, media, etc.
I like both I must say. the new MS Office one and the one used by OOO. I think people put too much empasis on these. I've got to say, even after their whole redesign of the interface, MS haven't been able to come up with an easy to use system to deal with styles and numbering hierarchy in numbered lists. OOo still does a better job at it, as it has for the past few years.
IMHO, it's much more important that OOo on Ubuntu looks like OOo everywhere else than it is that OOo looks amazing on Ubuntu - especially since you're not going to get any consensus on what looks amazing. (You may get a clear majority - but that's different from consensus.)
