Media categories allow you to sort and relate files by whatever you need. They can be uncategorized or in multiple media categories to suit any purpose. 
.
In the media section of a Card, you can easily add a file to a category, create a new one or edit existing categories. Start typing where it says "Add" to add a category to this file.
Search through and click to select from existing categories. If you have no media categories in the project or you need to create a new one, you can add one by pressing "Add/Edit categories" at the bottom of this window.
To create a new category, give it a name and hit "Add". You can add multiple categories from this window or edit existing categories by pressing the three dots next to the category.
