Google announced today that it has made some improvements to autocomplete predictions in Gmail. Specifically, they will now take into account the actual content of your emails.
"For example, you might now get lax reservation or lax united as predictions after typing 'lax' if you have received an email with a flight confirmation for your trip to Los Angeles in your inbox recently," explains Gmail software engineer Isaac Elias.
Google says it will be rolling out the improved autocomplete feature in English over the next several days. More languages will come in the next few months. It won't be available in Google Apps at first, but will be sometime in the future.
Last week, we saw Gmail get some new Google+ integration. This includes new Google+ profile picture displays for your Circles, and Circle support in search and filters. You can now find messages from specific circles by typing circle:[circle name] in the search box. You can also find mail from circled contacts by searching with has:circle.
In addition to that, if you conduct a contact search, results will now feature the contact's profile picture, along with the emails.
