Four months ago, Nick Kreeger announced the first release of Correo, a new open source email client for Mac — “Mac essence, Gecko powered” — that “blends technology from two popular Mozilla projects, Camino and Thunderbird, to create a polished native Macintosh application”.
The second public beta has just been released. Correo 0.2 adds several nice new features: Keychain support, Address Book integration, the ability to open messages in a separate window, attachment support, better message list support for IMAP accounts and a collapsable message header and attachment view.
Although Nick readily admits it is a work in progress, the interface already shows Camino’s good looks:
Address Book integration is the big leap forward for usability:
Also nice is the “auto-complete feature” in the To: and Cc: fields:
Underneath the polished exterior, it’s all Thunderbird. The account manager and new account dialogs will be instantly familiar to Thunderbird users.
And the rendering is all Gecko too, as the following ironic screenshot of the new “single window” mode illustrates:
Nick hopes to implement features as the app’s development unfolds, including, plugin capability (to allow development of extensions such as PDA synchronization) and a tabbed window interface.
