You can categorize tasks; when you receive them via e-mail, you have the option of sending them "TO TASK." In the following step you have a drop-down menu for classifying them by "office," "computer," "street," "objectives," etc. When you select the category, you have to use the "Save and exit" command.
Afterwards you can consult them by opening your TK System (for example, using the "Compass" button and then clicking Tasks to see them by Category (you will only see the ones you categorized). If you want to consult pending tasks, you can do so by viewing them, for example, alphabetically; you'll also see some completed tasks and the ones that are pending. You already know that you can't complete Compass tasks using the "Execute" button, but that you'll have to complete them on certain dates and in the different scenarios.
