Google announced that a few Gmail Labs features have graduated into actual features, and that it has made some improvements to advanced search in Gmail.

Advanced search now supports autocomplete predictions in the From: and To: fields, so you can find messages exchanged with specific people easier.

The three Labs features, which have graduated are: Refresh POP accounts, Filter import/export and Navbar drag and drop.

“With the graduation of Refresh POP accounts, clicking the refresh link at the top of your inbox will now not only update your inbox with your new Gmail messages, but will also fetch messages from any other POP accounts which you have set up,” Google said in a Google+ post. “From the Settings > Filters page you can download a file containing some or all of your filters or upload a file to create a set of filters all in one go. This makes it easy to share filters with friends, backup filters for later and more.”

“Lastly, if you use gadgets on the left-hand side of Gmail, you can now rearrange them with drag n’ drop,” Google added.

Last week, Google announced the launch of additional language support for improved search in Gmail.
