Labels
Labels are used to organize tasks in each project. A project can have as many labels as required. A task can also be given as many labels as required.

Create labels from the Labels
tab under the project page.
Each label is assigned a color to help make it visually distinct from other labels.

You can see all tasks for a specific label by using the label:name
search term. See search syntax for more details.

Categories
An interesting aspect of labels in deftask is that you can organize labels using categories. For any category, only one of its labels can be applied to any task. This makes them useful for things like task type (bug, enhancement, maintenance) tracking status (todo, in progress, done), milestones, epics, etc.
