I am using an Agile Board which is used to display several projects. I have one quick filter set for each of these projects.
So, when I use a quick filter to see only the User Stories of only one of the projects, I still see all Epics of all projects. As an Epic is only a task part of a project, I would be expecting that the Epics would be filtered as well.
The result is that I end up with a very long list of Epics and I have no way to filter them out.
