Simple Tasks is an application that allows you to organize your tasks in different folders and have them all in one place. You can create as many folders as you want to separate your lists more efficiently. For every task you create, you can type the desired text to identify the task, assign a category, and add a due date. The program offers three viewing options: you can display all the tasks, or only the active or the completed ones. Completed tasks will appear in grey and crossed out and active ones will be in red, showing the respective due date.
Unfortunately, you won't be able to customize the font, add reminders or alarms, or distinguish tasks with a specific color. The tasks can be imported from other programs and you can also export them. The program offers a very simple and nice user interface which anyone can easily use.
All in all, if you looking for a free task organizer, Simple Tasks may work for you. However, you can find more complete applications for the same purposes for free or a few bucks.
