Feature Suggestion - Better Collaboration

Consider a small to medium sized team using Redash for internal dashboards or business insights. Most likely multiple people on each team will need to modify dashboards, but adding each person to the dashboard, visualization, and query permissions would take up too much time. The current solution involves making everyone administrators. However, this seems less than ideal because now everyone sees others’ unpublished queries and dashboards.

Does anyone have thoughts on an “Internal” or “Sharable” mode where all dashboards, queries, and charts are editable by everyone in a group by default?
