So I'm a Jira newbie and creating my 1st project (we're using service desk cloud). When I took a look at my new project's details I noticed a field called "project category". I've searched the community and documentation, but I can't seem to find out exactly what the purpose of project category is. None of the other existing projects that I'm now in charge of use project category and I've confirmed that the previous project admins didn't use it because they didn't know what it was for. It doesn't seem like it's an integral part of Jira.
I guess I'm just curious why it exists and what it might be used for. Maybe it's something I'd find useful, but I really don't know?
