Agendl [uh-jen-tl] is a free task list manager.
Agendl is being developed by Niels Poulsen (nielssp.dk) using an MVC-based web application framework.
All icons used are from the Oxygen Project.
The official Agendl chrome extension is available at Chrome Webshop. It provides quick access to the list of your choice. At the moment it is still not possible to check/uncheck tasks using the extension though.
