There are 4 screenshots of what MUFFIN is, and it appears to basically be 4 types of toolbars, one of which is essentially a ribbon. This isn't really anything revolutionary, they just made up a stupid word to describe maintaining 4 types of UIs for people.
Honest, this is why Linux can't have nice things. Yea I know many people hate the MS ribbon-style stuff, or the OSX menus, but at least it's consistent (for the apps made by the same developers following the rules) and easy to maintain. I can guarantee that this MUFFIN approach will just result in 4 quasi-usable scenarios, each with bugs, rather than 1 well tested scenario that 80% of people like.
