It would be great if we could block/require a pagure issue in another repo so that we would get notified in our ticket when that issue gets updated. Going farther and allowing the updates to be configurable would be nice (only update if the ticket status change, or update on comments in other ticket, etc)

if you wanted to take it a step farther adding support for linking github issues would be cool as well. Should be able to do this using the github API.
