Side note: one thing we need to revise a bit is the order of transformations. Headings and List should probably come first, for example. We might also want to restrict certain transforms to the case where the length of a paragraph block is < than some characters — it doesn't make sense to convert a full paragraph with multiple lines into a button, for example.

Maybe also checking if a paragraph has more than one links?

It renders based on the usage so I think this is the current expected behavior. If we want to change, this may be a follow-up issue.

I didn't know there was a way to do this. Any suggestions on checking length before showing the transform option in the transforms list?

Do you mean if more than one link then it transforms to multiple buttons or if more than a link then do not transform?
