I’m currently using a Grid Card to display my AC controls. When I click on the details for the card, I notice there are more options which I’d like to display on the “main display”
This is not about configuring a Grid card.
Grid card is just a container which may keep different cards (History graph card, Entities card, …).
What you should mean is a card which you placed inside the Grid card.
Suggest to find out a name of this card → rename your thread accordingly.
