I have an entity filter that shows me all the lights/fans that are left on and I usually check this before going to bed or leaving the house. The problem I have is sometimes I turn off an entity and end up closing another wrong one by accident because the device disappears so quickly once turned off and shifts everything up. Is there a way to introduce a short delay before the device disappears from the list?
A possible direction: try playing with a CSS “transition” property, use card-mod to access it.
No, do not think this may be fixed by CSS since the whole row is ether present or not as a result of some internal “filter” method.
