If you use several Google accounts on a daily basis, you probably want to be logged into all of them at the same time, but to achieve that, you have to use several different browsers.
Now, according to Google Operating System, Google is testing a feature that will let users be logged into multiple Google accounts in the same web browser. Personally, I have at least four different Gmail accounts opened at all times, and this feature is very high on my wish list.
Judging from the screenshot below, Google services that are currently supported are Gmail, Reader, Sites, Calendar, Code and Docs. There is also one limitation: if you turn on multiple sign-in, you cannot use Gmail’s offline mode.
