I have been using Thunderbird 2 for more than 2 years now, I recently upgraded to Thunderbird 3 and found it very well designed. Here is what I liked:
- Has an attachment reminder, so if you write “please see the attached… ” and then forgot to attach, it reminds you. Neat!
- Tabbed emails. Used to tabbed browsing? welcome to tabbed email. Allows you to open emails and mail folders into different tabs.
- Powerful search. You can type a search string, and it will find that string in inbox, sent box, subject. This is quite useful if you are looking for something but don’t know where it could be.
- It also has smart folders and and archive folders.
- Addon manager to manage all your addons.
Here is a complete list of features.
Ubuntu 10.04 scheduled to be released on April 29,2010 already bundles Thunderbird 3.
