Keeping dashboards for multiple peoples devices and one main for tablet views is a chore if you make any meaningful changes like new hardware or replaced device.
What I suggest is savable card “templates” that when you make a change to it it then gets updated in all your dashboards.
Say you make this amazing card for lights you then copied it to all your dashboards but you then decide you don’t want one of the lamps in that room and it would look better in another. You now have to go edit all the cards in all your dashboards to move that lamp.
What would be better is a “template” card that you just have to update once and its then applied to all dashboards at the same time.
With how nice Browser Mod is you are forced to have personal dashboards for everyone otherwise you get popups happening on other devices at the same time.
