A Useful Planning Tool

I recently heard about and started using a tool called Trello. Trello has boards that you can organize into lists and put cards inside lists. I started using Trello for tracking my tasks using three lists - TO DO, DOING, and DONE. I also use Trello to manage my homework.  

Trello is also a collaboration tool that you can work together with friends/colleagues.
