When I create a cover group that contains two curtains, it will have the icon of blinds. It should instead have the icon of curtains.
I can of course override the icon of the entity, but that will not give me an icon that changes based on the state. There are still several ways to get the right icons, but hey are complicated workarounds and it would be a lot better if it just chose the right icon and I wouldn’t have to bother with changing it.
