Would be amazing if you could reuse a lovelace card you have in other places without duplicating it.
For example, I have a dashboard with a side view panel that I reuse under all my tabs. I constantly update it with features and right now I have to duplicate it and paste it to every tab when updated. Would be amazing if you can can create a card and link it to a master card so when I update the master card it updates it in all other places.
I know there is a custom add on right now but you have to copy paste the yaml etc and it’s not user friendly at all.
