Actually, for me this is a perfect example--since I hate the combined search/URL bar in chrome. I'm conditioned to type urls in the URL bar, not search queries, and the only matching I want done is against the urls in my history. So instead of typing "hacker" I type "news." and usually, hacker news is way down on the list until I type "news.y", and even then on some browsers, it doesn't appear at the top (even though it is the only thing in my history with a URL that has that pattern in it.) This Ubuntu HUD would worry me heavy GUI apps like GIMP that have organically developed relatively complex menus. It seems to be a good thing to be able to search for the menu item, but having to remember all the different menu names could be problematic, not to mention the dependence on the keyboard on a app that is primarily mouse driven. I'm assuming context/right click menus won't be impacted by this?
