I would love to have a column for who the viewers are for a dashboard, on the dashboard list page. This would allow me to know who to reach out to if I wanted to delete or update a board, easily see which boards were missing a key group invite, and generally just make it easier to manage viewership subscriptions. Currently, you need to open each Dashboard and load the "Share" button to see who it's been shared with, which is a bit clunky.
