FusionDesk

If you are looking for a simple tool to help you organize your tasks, then FusionDesk is a good option to try.

This program has an easy-to-use interface where you will be able to create multiple projects with many tasks, and easily track the status, priority, and many other aspects of the projects, in order to organize your time in a better way and get better results.
Creating a project and setting new tasks can be easily done on the program interface. You can add as many tasks as you desire on each project. Besides, on each task you can set the status (not started, in progress, waiting, deferred, completed), the priority (low, normal, high, very high), start and due dates, tags, contexts, and an estimated time in days, hours and minutes.
On each project you will be able to add new folders and sub-folders, so you can set and track big projects with multiple tasks and keep them perfectly classified. Moreover, you can also make backups of your projects.
In addition, you will also be able to export your projects to four different file formats: Plain Text, Excel CSV, RSS and Quick Books.
