Editing the visual part

[devopg]

Just to ask. Is it realistic to add a new feature so that you can not only edit the markup, but also edit the visualization?
Or is it necessary to change almost everything?

I'm sorry, this feature cannot be achieved currently, because there is no good mapping relationship.

This is the foundation of editors like Typora. It's awesome but no time to study its principle. If there is time later, I may try it out.
