Hello, if you look at Metabase or redash or kibana even the free versions, they all allow easy multiple dashboards for the user, and let him share the dashboard configuration with another user.
Multiple Dashboards: Tabbed Dashboard option with Edit modes, Sharing / more efficient - both horizontal and vertical views.
Dashboard setup Sharing: When a user configures his widgets/charts and dashboards, he wants to share the same configuration with others in the company. You need to allow an option to share the link. The second user can consume the same dashboard (but with his own data permissions)
