What are user stories called in Scrumwise?

People use many different terminologies in agile and Scrum, but Scrum itself uses the term "backlog item", which can then be either a feature, bug, etc. That's why we chose this terminology in Scrumwise.

A "user story" most often means a feature, and in that case is represented as a backlog item of type "Feature" in Scrumwise. Or, if it's a bug, use type "Bug" instead.
