Those brilliant bright guys at Gmail Labs don't seem to have enough rest these days, they just keep on churning up new features for Gmail every now and then.
Just few days ago we received SMS text messaging for chat feature in Gmail (which our own fellow Associate Writer Lauren Blake is loving it), and now we got an experimental feature in Gmail that turn an email into a Google doc with one simple click, "Create a document" converts an email into a Google Docs document.
Jeremie Lenfant-Engelmann from Google Software Engineer announce the new experimental feature at Gmail Blog: No more copying and pasting the text from your email -- just open the message you wish to convert, click the "Create a document" link on the right side of the page, and voila, you have a brand new document which you can then modify and share!
You can easily open up a blank doc by hitting g and then w (just make sure you have keyboard shortcuts on). To turn on this feature, go to the Gmail Labs tab under Settings, select "Enable" next to "Create a document" and hit "Save Changes" at the bottom.
