As admin, I can get other people's dashboards using the /dashboards/admin endpoint.
However, the information returned is limited: I can't get a .dash file or widget objects.
I want to use my admin rights on the /dashboards/{id}/export/dash endpoint to download every dashboard, even ones that haven't been shared with me.
Perhaps this could be generalised to other endpoints that limit based on dashboard permissions or other permissions: If as admin I can grant myself access to an object through the UI, then I should be able to set a flag in my API calls to circumvent these restrictions.
