I just noticed it too. Yeah, it gets pretty old with open blah blah. Latest beta is a bit different, but i think they missed the point with commands and launching and sticky argument window. If they are making me hold the damn caps lock key then I expect to be over with it in a few keystrokes (and without Tab etc) but typing open or o <tab> window is just too much.
Commands with selected text are great, but it's a but cheap with just lowercase and uppercase. I love that it doesn't use the clipboard for that functionality, though.
I love the learn functionality.
