Google has launched a few new features for Gmail for mobile. These include: multiple sign-in support, mobile-specific signature and vacation auto-responder.

Google has offered multiple sign-in for for the desktop for a while, but mobile users have had to get by on one account at a time. To do so, just click the account switcher at the bottom of the threadlist and click “sign into another account”. Then you can switch back and forth by selecting the account from the accounts menu.

“As part of added multiple sign-in support, we’ve updated URLs so that each account can have a separate bookmark,” Google notes. “For those who have previously bookmarked Gmail for Mobile, please update your bookmark.”

You can now set your auto-reply message from the mobile interface. It works pretty much the same as the desktop version.

Google gives a pretty good reason why you might want to use the mobile-specific signature feature. “We know that autocorrect and other mobile spell-checks can be frustrating as you are typing on the go,” says mobile software engineer Dominic Leung. “Let your friends know that you are responding via your mobile phone so that they understand why you might have sent a message that you are meeting for ‘monitors’ and not ‘mojitos’.”

To set up a mobile signature, go to settings, choose a signature, and check the box to activate it. Just uncheck it in the future if you want to disable it.
