I don’t really like the To Do lists that were added to Mail. I just don’t care for my To Dos being in my inbox like email. So, I was really excited when I found Anxiety, a handy, slick little To Do list application for OSX that both stylish and easy to use.

The program does integrate with Mail and iCal if you like, but it is also highly customizable. The visibility of the list window is there when you need it, and invisible when you don’t – and best of all, the application if Free.

It’s Leopard only – and you can download it right here.
