For the travel bugs here comes yet another google woogle .. magic trick. Now add your location along with your signature in the mail. This could be a very good tool for the ones who want to keep people posted about their location but a very nasty ones who are lying to their bosses and friend about the whereabouts. .:D ..
To try it, turn on Location in Signature from the Labs tab under Settings, then go to your signature preferences and check the box next to “Append your location to the signature.”
Although for an accurate location detection, make sure your browser has a version of Gears that supports the location module.
All i can say is thanks google for another trick
Google added a new feature to Gmail Labs today: Multiple Inboxes. Created as a 20% time project by Google’s Octavian Cost ache, this new feature allows you to expand your standard Gmail inbox with additional panes. The name ‘Multiple Inboxes’ is misleading, however. In reality, this new feature gives you something akin to multi-pane viewing, with your main inbox on the left and up to nine other ‘inboxes’ on the right. These additional inboxes can display anything from searches, to mail with a specific label or from a certain sender.
You can use any of the standard Gmail search functions like is:starred, label:abc, or has:attachment to define a new pane.
Showing the new panes on the right works best when you have a wide-screen monitor with a relatively high resolution. Otherwise, the additional ‘inboxes’ take up too much space and you won’t be able to read the subject lines of your incoming messages. If you add a lot of new inboxes, this will also make your screen look extremely cluttered.

You can also chose to have Gmail display the extra inboxes underneath or above your standard inbox, though this method probably works best when you set Gmail to only show a small number of messages in your standard inbox.
This new feature will surely help those of us who get a lot of email to get a quicker overview of our incoming mail, but given the name, we had hoped that it would allow us to combine multiple Gmail accounts into one, which would be even more helpful for those of us who manage more than one email account through Gmail.
