uncomplex has released a public beta of Mailplane 2.0, an upcoming revision of its Gmail client. The app is effectively a site-specfic web browser, and is intended to make Gmail more seamlessly integrated with Mac OS X. Users can for instance quickly browse and attach files from iPhoto and iTunes libraries, and convert or resize images as necessary. Multiple Gmail/Google Apps accounts can be switched to without signing in and out, and the app can bet set to launch directly from Address Book, Safari, or anything else with a "mailto:" URL.

The v2.0 beta supports "Gmail 2" add-ons and shortcuts, such as Apply/Remove Label, and Navigate to Label. E-mail attachments can now be created from the clipboard, and account notifications have been improved, incorporating a "do not disturb" mode. Mailplane runs on Mac OS X 10.4.11 or better, and costs $25. The final v2.0 release will be free to registered v1.x owners.
