This is a pretty cool feature if you work on specific websites for people. It tracks your time on each task. This would also be good to use with students for them to track and understand ACTUALLy how much time they are spending on task and how much off task!
I used this greasemonkey script to hack my toodledo to look so much cooler with the contexts on the left hand side. This is a MUST INSTALL if you use Toodledo because of the layout and also because of the highlighting it does by context. WOW!
