First Look at Thunderbird 3 Alpha 1

[Poosc]

Heres a review of Thunderbird 3 Alpha 1

The latest version of the free, open-source email manager, Thunderbird, is in the wild—in an alpha release rough enough around the edges to earn the code-name "Shredder." It doesn't have all the features promised for Thunderbird 3 yet, but you can see where it's headed. I installed "Shredder" in Windows XP, and I'll show you what's there, and explain what's coming soon, after the jump.
Note: In case it wasn't clear from the introduction, Thunderbird 3 Alpha 1 is very rough indeed—the developers have all but promised you'll get crashes, bugs, and feature conflict. You could, if you wanted, install the alpha to a different folder than your current T-bird setup (be sure to choose "Custom installation") and back up your current Thunderbird profile ( more on that here), but "Shredder" might still give you a headache. If that's cool with you, you can grab the first alpha build at Mozilla Messaging, the spin-off Mozilla group now in charge of the email app.
On to the good stuff. Installation was pretty familiar territory in Windows, and I was relieved to see that Gina's guide to Using Thunderbird with Gmail IMAP is still valid. Once your account is set up, you land at a pretty familiar sight, at least in Windows:

What Windows users won't see is that the OS X version of Thunderbird 3 uses Macs' native Cocoa styling for a more integrated look (a Wired preview has a rough screenshot). And on every system, Thunderbird is using the Gecko 1.9 rendering engine, the same back-end that saves memory and moves a bit swifter in Firefox 3.
The most obvious wholly-new feature in Thunderbird 3 is an option for opening new messages in tabs. In "Shredder," you have to do this with a right-click on messages in your inbox, but we'll assume this can be a default option, or a keyboard shortcut, in the final release.

The other new feature that might give Thunderbird power-users a smile is a Firefox 3-like add-ons manager, which lets you search for Thunderbird-specific extensions and install them from within one window, rather than hunting on Mozilla's site, right-click saving, hitting "Install" and so forth. You can also manage plugins like Flash and multimedia handlers from this window.

Mac users get another long-awaited feature with Thunderbird 3's ability to integrate with the native OS X Address Book. This rough feature is disabled by default, but developer Bryan Clark posts a work-around for the adventurous.
A few more features look promising in Thunderbird 3, but I wasn't able to grab photo evidence (or the evidence just wasn't very exciting visually). They include:

• Better integration with Lightning, the nifty calendar manager that can be a bit wonky as an add-on in Thunderbird 2.
• A chance for more powerful third-party extensions through a new API dubbed STEELE.
• Better search functionality, with a promise of fewer false positive matches and some multi-lingual awareness.
• Extensive code cleanup throughout the app (well, when they release the final, we'll assume), and improved crash and bug-reporting tools
