I've noticed that the newest quick entry dialog closes on "enter" now, instead of just control+enter, like the last version. I was surprised by the change, since I was using enter to add more than one line item. I figured out that "shift+enter" will work for that purpose.
I'm not complaining, just curious why you went all the way to having enter close the dialog. Was this something that people were requesting? Like I said, just curious...
