This is a little bit complicated perhaps but I think it would be really helpful for working between YAML and the visual UI when creating and editing dashboards.
Take an example Home Assistant dashboard which, over time, might become pretty “crowded” with many different tabs:
I could draw a lassoon around a part of a tab or alternatively enter some kind of selection mode in which I can hold down perhaps the shift key and select multiple elements simultaneously.
And how would you select the YAML setup for that?
Just cards, so no element control or horizontal stacks in a vertical stack or vertical stack in a horizontal stacks or a grid layout and what grid then?
