The best thing that has happened to me regarding time management is Toodledo. Similar online time management tools don't come close.
The SECOND best thing was TaskUnifier! TU is an offline time management tool that can use the Toodledo online service as a cloud database.
The third best thing is that, after devoting enormous effort for several years to make this a remarkably mature and full-featured standalone product, is that Ben LeClerc has "abandoned" it to the public domain.
Through his dedication and selfless sacrifice, he has demonstrated his enormous talent as a developer and his skills in project and product manager.
More importantly though, he as also shown enormous character, compassion and generosity in allowing others to continue to benefit from his enormous investment of time and effort, rather than "scorching the earth" as many other less mature and respectable developers have.
Unlike super giants like Google that abandon user's who have come to depend on their product offerings, TaskUnifier lives on - at least for capable developers - thanks to Ben's selflessness and integrity.
Many, many thanks, Ben. My pathetic registration years ago seems like such a pathetic gesture considering your dedication and professionalism, but please accept my thanks for one of the best time management (and more!) tools I've ever used!
You will be remembered!

Toodledo provided an awesome online tool for time management, usable from any browser, and many mobile apps. TaskUnifier leveraged this fantastic product by adding new time management capabilities, exceptional UI/UX, customization and so much more. Without doing either a disservice, if Toodledo is the Oracle of Time Management, TU is like a web app such as Facebook, leveraging other technologies to provide unique and vital capabilities. TU allows you to abandon the clunkiness of the web app for the convenience and ease of use of a native app. It's enormously extensible search mechanism, intelligent defaults, and enhancement of the native information Toodledo provides makes the combination of the two wildly powerful. Besides being easier to use, more full-featured, and a classic example of elegant, clean design, throughout the life of the product Ben worked tirelessly to support TU and his user community)
