A new update for Mailplane, an email client for Mac that's dedicated to Gmail, was released today. It sports a handful of bug fixes, integration with the Mac address book, and support for six new languages. An "iMedia browser" was added that allows users to drag and drop pictures, music, and movies right into an email without opening the associated iApp. You can even create a new Gmail account right inside Mailplane, and if you download a lot of files via Gmail, you'll also like the new feature that cleans up the download window at the touch of a button.
Though Mailplane is still in private beta, you can apply to be a tester.
