Taskwarrior scales to fit your workflow. Use it as a simple app that captures tasks, shows you the list, and removes tasks from that list. Leverage its capabilities though, and it becomes a sophisticated data query tool that can help you stay organized, and get through your work. Taskwarrior is methodology-neutral. Whether you follow GTD, use the Pomodoro technique, or just do whatever works for you, Taskwarrior provides capabilities to help you, not restrict you. Taskwarrior is an active, vibrant project. In the last year, it has averaged 5.58 changes per day. Taskwarrior enjoys lively participation from many contributors, with currently over 60 providers of code patches. But there are even more contributors (252 of them) helping out with documentation, bugs, support, ideas, requests and extensions. It's just going to keep getting better.
