.story vs .storytemplate vs Team Slides in Storyline 360
I'm trying to understand when / if I would ever save or share a course as a .storytemplate file, or why that is, or ever was, a necessary feature.
I have a small team of ID's. Before 360, if I wanted to send them a course to build off of, I could simply send them the .story file. They could import it and away they go! I don't see where .storytemplate files would be needed in this scenario.
Now, with Storyline 360, the concept of .storytemplates seems even more unnecessary. Now, I can simply send my team the .story file as before, or load it into the new "Team Slides" folder and they can access it from there.
Am I missing something? Why would we ever need to share something as a .storytemplate file when we could simply email the .story file back and forth or just load it into Team Slides?
