I propose that groups be implemented. It would work similarly to how the option for “admin only” can be applied, except that option would be replaced with “Available/Visible to Group” and then you would select which groups could see that dashboard. I suppose having a dropdown with checkboxes for individual users would also work though. I’m a Windows admin so groups is what is familiar, hah.
With this option I could end up with multiple dashboards in the side panel that no one else could see any cards on as it’s intended for admin only, yet the non-admins will still have to scroll past it as blank dashboards which would clutter up their view. What you suggested is not the same as the feature I requested.
It seems like a no brainer, and very useful. If I create a kiosk for the front hallway, and a user named Kiosk, I want them in the Kiosk dashboard only.
