Changes to Treatments update live. This means there no need for saving, no version files, no outdated decks. When someone who've made an Editor is in the Treatment with you, their changes appear as they make them, and you'll see their profile on the Slide they're working in. If they're outside your current view, an arrow points you toward them.
