At #3 suggestion, You mean the same old Office Plugin that allows user to open Office files in web browser? Those are evil IMO, I am glad they no longer do browser plugin. I don't hate plugin, I hate how people use it and causing a lot of problems.

As for ribbon, it is too thick. But yeah, if toolbars are done in that way, the thickness is locked in. I agree. This is probably better. They could default MiniRibbon instead of expended ribbon.
