How do I make these? Under the tags tab I formed a tag group then I clicked on a tag and asked it to merge with a parent group.... but it deleted the tag all together and my tag group still isn't able to be applied to files/folders.
Nvm I just figured it out completely by accident.
For future people with the same question select the tag group (right click anywhere in the box) and click add tag then it will form the hierarchy under the tag group. If you just want to add a new tag make sure that the tag group is not selected when right clicking.
