[IsmailKemmoune]

Describe the feature you'd like to request

I wanted to style each heading level with it's own styles.

Describe the solution you'd like to see

I found a solution on Tiptap to style each level using extend and mergeAttributes, I would like a similar or a simpler way to style each level.
