Playing with the tool! Really enjoying it so far.
One thing I’ve encountered a couple times is that often I need to transition to a state but with a negligible difference. An example would be to go back to a previous state with an error message. In a formal sense this is a separate state, but when all the available actions are the same it can really clutter the spec and the diagram unnecessarily. So far my approach has been to add a comment, but this feels a bit buried. It might be nice if there was a simple way to note in the spec to go to another state, but with a modifier.
