Unity is better in 12.* than earlier. No clicking - just hit super (or super-A, type for example "thENTER" for thunderbird. Took me a while to rid my brain of the notion that I *needed* a menu, but now I like it.
Or ctrl-alt-T for terminal.
Still despise the stupid idea shared by Gnome3 and Unity that you're ever only going to want one window of each type and you need right click + "New Terminal" or whatever to get a new one.
