Option change icon for state ex. open and closed

[pepsonEL]

Hi
Good feature will be to add option change icon for entity for all his state.... example for binary sensors which is from Window good option will be if we can chage icon also for state open and also for state closed. Now we can do it only bu create sensor template. But it create next entity.... and in this situation in HA user has many many many entietes.... Then search correct entity is no good and no friendly. Change icon for all state will be very good solution.
