Per description provided in David Allen’s “Getting Things Done”, categories (aka contexts) are used to categorize your tasks/actions by places, tools or people required for the task completion. One of the best examples is a “phone” which can be a tool needed to complete tasks across many projects. The basic goal for them is to allow you to group actions and do them in bundles unrelated to the project, but related to a particular person or a place or a tool used.
Categories are right below your project list in Nozbe menu and they work in a similar way to projects.
There are two ways to create a category.
1. Use the “+” button on the category list
The simplest way is to create new category directly in the list:
In the categories view (1), just click the “+” icon (2). Text input window appears at the top of the list (3).
Type now the name of a category and click “Save”. Please note that per default “flag” icon is added, to change it you will need to edit this category.
2. Create a category in the task parameters view
Second way to create a new category is available when changing categories in an existing task
An input window at the top of the list appears. Here, we write a name: “experimental category” (3).
You can add a category by simply using the hashtag formatting while creating a task. The system will automatically show you suggestions when you enter a # and a few first letters.
Please note this will only work for already existing categories and once you save the task, it will bear given category.
The second way to add a category is by choosing one from the details (2) of a task (1).
This will require you to pick one or more categories and confirm (3). At that point, all selected categories will be added to your task.
If you wish to remove a category from the task, just go again to the details of the task, click on the button now stating given category name, unmark it in the list and confirm.
When you choose a category from your categories list, you can see all of the tasks across all the projects with this category.
You can also edit the category information and access additional options of this view by accessing the “info bar”:
You can manage multiple categories at once in the “Edit” mode:
Note: In the “Edit” mode you can also edit each category name in-line. Just click or tap on the name of the category and change its name.
Changing icons or colors of categories
Here’s how to change multiple categories’ parameters:
Note: By default, all categories are given no color and the 1st icon from the menu (“meeting”).
If you add a category to a task in a shared project it will automatically become shared with project members. They will also see the category icon that you selected but no color. Color of a category is individual, and each project member can set his color for each category.
