Tags give you an alternate way to create sets of Tasks regardless of where they are in your Master List. When adding or editing a Task, you can choose one or more Tags to assign to the Task.
For example, you might have a few different projects in your Master List related to improving things around the house. Inevitably, there is a sub-task in each of these projects to get something from the hardware store. For each of those sub-tasks, you can assign a Tag called “At Hardware Store”. This way when you do go to the store, you can see all of the things with that Tag and reduce the number of trips you need to make. Wouldn’t that be nice?
You can view the set of Tasks with a particular Tag by using the Filter View. Simply choose the Tag as the filter for the Filter View. See Using the Filter View to learn more.
When you are assigning Tags, you can create a new Tag if it doesn’t already exist. To manage your Tags, choose Edit Tags from the system menu. There you can add, edit and delete Tags.
