Uncomplex gmbh has released Mailplane 2.2 ( http://mailplaneapp.com), a new version of the Google Mail client for Mac OS X. The upgrade adds support for Gmail's Priority Inbox, improved attachment downloads, integrated Rapportive and TrueNew plug-ins and more.

Acting as a site specific web browser for Google's Gmail, Mailplane is a full fledged Mail client for the Desktop. It integrates the Gmail web interface into the Mac experience. It supports multiple Gmail and Google Apps accounts and lets you switch between accounts without the need to sign in/sign out from the Gmail accounts.

With iLife integration, you can browse and attach files from your iPhoto and iTunes libraries. Downloads can be directly imported into iPhoto as well. The integrated screenshot tool lets you take and attach a window, screen or region.

You can drag and drop files and images on the dock application icon, or any Mailplane window to create and upload attachments. With automatic photo optimization, image attachments can be converted and resized to make the message even smaller.

Mailplane can play a user defined sound, as well as show the number of unread messages in the application icon, account drawer and status menu item. As Mailplane monitors all Gmail accounts, unread message counters and message subjects are displayed for each account.

Mailplane is Universal Binary so runs natively on both PowerPC and Intel Macs. It requires Mac OS X 10.4.11 or higher. A demo is available at the Uncomplex web site.

A single user license costs US$24.95 and may be used by a single person on two Macs. A family option (five users in same household) is $8. Educational discounts are available.
