Script Menu
Erik Barzeski shows how to make a script menu that includes the scripts for the frontmost application inline instead of just having them in a submenu. It’s not OSA Menu, but it’s getting there. (How about holding down Option to edit the script or assigning keyboard shortcuts to scripts?)
Unfortunately, Script Menu uses the annoying “disabled menu item as a label” trick that’s also seen in the Apple menu, iTunes, Mail, and Safari.
