Zeplin - Numbering screens

Video here: https://www.youtube.com/watch?v=Ll2UE-F4OJE

This is a quick prototype I made with Sketch and Principle to show a new feature I would like to see in the next Zeplin versions.

Screen numbers allow you to mark each screen with a number without renaming them one by one.

In this prototype, you can see how you can show or hide screen numbers.
