Because Klar uses Issue Fields to store information from your refinement, this information is available to search with and create filters from. So, if you want to have a saved filter for all issues in a status that have an External Dependency value of, say, “Marketing” then you can do that and much more. This page tells you how.
The issue fields available are explained in more detail here: Viewing fields on issues
You are able to use these fields in the issue navigator
