Hello,
In v1, Alfred would perform a Google search if you hit command + return with any value in the search field. This was handy if you were trying to search for a URL, or something else that triggered a different result within Alfred.
In v2, that's no longer the case - Command + Return just kills the search box, without doing anything.
It's driving me up the wall, since I used that feature many times a day.
Thanks!
Edit: ...and I'm an idiot. Searching through the preferences found it hidden away in the Advanced pane.
