I found both the `severity` and `severity rationale` fields on my project's settings->fields list, but that page says those fields aren't set to display anywhere, and there's no screen link to make them visible.
Whenever I go to any configuration or configuration scheme I can't find those fields anywhere to assign.
I've tried going to a bug and clicked on "configure" to see if I could add it there--but no luck.
I must be missing something basic because I'd expect most bugs to have a way to indicate severity separately from priority.
