Awesome app. Allows for custom lists and allows collaboration on ones you specifiy for group projects/tasks. The interface is clean, crisp, but also allows you to make it your own by adding color themes to the accents of the task pages. The only thing I wish this would include is a customizable "smart list" based on certain parameters. This would make the app even better, though out of the box - this has everything you need to get your tasks and projects done!
