Gmail Scribbles

Gmail's app for iOS and mobile Gmail added a cool feature that's not even available in the desktop interface: Gmail Scribbles. "You can now open up a canvas and scribble a message that will be attached to your email. It's perfect for sending a quick sketch that is hard to express in words or adding a fun graphic to make your email more personal. Scribbles support different colors, brush sizes, lines, erasers and spray paint." Maybe Scribbles is just a sneak peek at an upcoming mobile version of Google Drawings.

Gmail 1.1 for iOS also changed the notification sound, added better support for nested labels and Google+ Circles. The settings page that was available in the mobile web app, is now included in the iOS app, so you can add a custom signature and a vacation responder.
