Redmine

I like how you can assign a category to an issue... but that's a pretty standard feature for an issue tracker. For one of my personal projects when adding a new issue I often find myself spending extra time trying to decide which category it should go in. Admin? Site features? User experience? UI? In some cases more than one apply. I notice that the newer issue trackers such as Lighthouse now let you assign multiple tags to an issue, and I really wish Redmine let you do it too. Has this been considered yet? I'd be interested in adding this feature myself if people are interested.
