Toodledo Web-Based Todo Manager

Webapp Toodledo is a free and featureful todo list manager written by an independent developer.

Using Toodledo you can add priority, due dates and notes to each item in your task list and organize them in folders. Export your list to XML or plain text and subscribe to its RSS feed. You can even set up recurring tasks and multiple lists. Toodledo isn't as pretty as say, Tada Lists, but it has convenient inline editing and does seem to trounce all the web-based todo list manager competition in terms of features. If I were to write a web-based todo list manager, Toodledo would be it.
