Undone is a productivity tool that lets you manage your 'to do' lists and the bigger projects that they belong to. Get your projects out of your head and onto a list! Undone makes it easy to add and edit projects as you need, and you can add as many actions as you need for each project. Organise and tag your actions however you want. Now you can optionally share some or all of your actions with friends and colleagues with RSS feeds and Widgets.
