It would be super helpful to have the option to add a button as part of the empty state, for list blocks and list details. It’s a common (and recommended) practice for product design, since it invites users to create content.
For example: if you’re seeing ratings for a movie, an empty state would say something like “This movie hasn’t been rated yet. Be the first!” and then a button right below.
I know this can be done with custom code, but I would bet it’s a common use case.
