Feature request

Hi !

First thanks for this usefull extension :)

I have a little request, I use it for view easly colors used on my project. It's possible to have some color preview like this extenstion ?

If it's not possible, maybe support some html block to use background css feature ? (I'm on cursor)

Edit : and a render of image `![]()` don't work :/
