Latest Thunderbird rolls search changes
Mozilla released a major update Tuesday to the beta build of its desktop e-mail client Thunderbird, debuting a new search feature, "smart" folders, an activity manager for monitoring communication with your mail server, and better Gmail integration among the list of improvements. Thunderbird 3 beta 4 is available for Windows, Mac, and Linux.
The smart folder view condenses your various in-boxes into one gestalt in-box, but it's easy to switch back to the traditional view if you don't like it. In the folders pane, use the left and right arrows at the top right to change your folder view until you're looking at the one you prefer. Thunderbird will remember your last setting, so when you restart it won't jump back to the smart folder setting. If you have multiple e-mail accounts, though, this should make managing your e-mail stream much easier.
