The use of tags is a unique feature for each user, designed to establish specific rules for the use of tag colors.
For instance, you might use red tags for topics you want to discuss in an upcoming meeting, yellow tags for topics that require analysis, and so on.
Tags can be found in the last column of the list view and at the bottom of the card view.
