It is nice that we have an option to create a pseudo class for each element and I think that it would be also helpful to have an option to delete the newly created pseudo class to keep code lean.
Use case:
I created a button element and duplicated it 3 times. Then I applied a :last-of-type pseudo class into the button element. However, then I decided that I don’t actually need that pseudo class but there was no option for deleting it.
