More Crowns, e.g. diadems etc

I love your application and have used it many times over the years. I do not wish to impose on you and do not know how active you are with this project these days or how hard it is to add new charges, but it would be extremely useful to an upcoming project I have if you could include more simple crowns/coronet/diadems, similar to some of the baron/knight/lord crowns depicted in this Wikipedia page under Italy, Spain and France. https://en.wikipedia.org/wiki/Crown_(heraldry)
