Currently, there isn't any way to inform or restrict a user from adding undesirable content. We have multiple fields where we'd like to enforce soft/hard limits e.g. maximum character limits.

We'd need at least four states inform, warn, error, and success where we can change and style different messages such as "Oops you've added 35 characters but only 30 are allowed."

Also, it would be great to have the ability to disable the publish button if any field currently is in the error state preventing a user from publishing erroneous content.
