How do Storyline beginners overcomplicate course building?

I've seen the "layer in place of a slide" too. To me, it reflects an unclear vision of course structure. A slide is not just one of any number of unnumbered places between the beginning and the end of a course; a slide is a point in the itinerary where the user does a particular thing. What that particular thing is should be an integral part of the course. 

I've also seen the "object names not given meaningful names" problem too. No, having a slide with default object names isn't helpful after you get past a few objects. This wasn't a problem for me, but then again I'm both a programmer and a writer, so I have a bias towards naming things. 

Lastly, I've seen the excessive use of X (usually animation). This one comes from not having a good grounding in instructional design. Often, course designers do things because they can, not because it serves the needs of the course.
