In order to do that I need icons.
currently I have:
icon.png
icon_small.png
To do what you want for a particular bracket I need (brackets that do not want to show open and close could omit the open and close):
icon.png
icon_open.png
icon_close.png
icon_small.png
icon_open_small.png
icon_close_small.png
I am not a fan of making lots of tiny icons and trying to position them just right. But I will make everyone a deal. If someone provides all the icons all lined up nice and with the size variants, I will add the functionality . Deal?
