Thunderbird 2 includes several new features to help you manage your inbox. As you receive email, Thunderbird 2 will help you organize the most important messages to get you through your day.
Message Tagging
Thunderbird 2 allows you to “tag” messages with descriptors such as “To Do” or “Done” or even create your own tags that are specific to your needs.
Improved Search
Thunderbird 2 features a new find bar that speeds up searches within displayed messages. Thunderbird also offers quick search, which starts showing search results as soon as you start typing in search terms.
