I like to work in index cards, so I’ve been keeping mine in Crazy Wall recently. I mean, why not use Crazy Wall to manage the app’s user stories?

The whole app is built with the idea of you adding your own notes to your walls. So, I’ve been using Crazy Wall to keep tabs on the features I know I need to build for the next release.
You could even go into crazy mode and make some ad hoc kanban swim lanes to keep your pile of work moving. Keep your backlog, workflow and progress displayed on your desktop.
