New Ubiquity Command: make-new-doc
This one’s useful for anybody that uses Google Docs. It allows you to skip the main screen and go straight into a new document, spreadsheet, presentation, or upload. More information at the link.
(update: It doesn’t seem to work on my laptop, despite working on the other two computers that I’ve tested it on. Instead it takes you to the menu. If you try this command, let me know if it doesn’t work.)
