Back in August (2005) I wrote about MailTags, a great utility that extends the functionality of Apple’s Mail application. The new version (1.2) is out, and it has some great new features… like the ability to create iCal ToDo’s from within Mail’s interface. Check out this review over at Hawk Wings for a more in-depth look at what’s new.
The same developer also makes Mail Act-on, which is a great utility for adding keyboard shortcuts to Mail.
MailTags and Mail Act-on are donationware, so they’re free to download and use without restrictions. If you like them, consider making a donation to help support continued development.
