I create a lot of dashboards and I find it cumbersome to make each filter shared and then make the dashboard shared. I always get ping by users that certain filters aren't shared. It seems to me that Atlassian should have a checkbox on the Edit and Share Dashboard screen to force Share inheritance or at least there should be some visual display indicating if a filter is private/public.
That said, before I open an improvement request w/ Atlassian (maybe there is one) has anyone found another way to deal with this?
