The code highlighting was a big one, but I also had issues when updating raw HTML. I would create a code block in raw HTML and then go to update it later. When I updated it, the elements that were there previously would be escaped after updating. So any time I needed to update raw HTML, I had to recopy the entire snippet since saving it would mess up what was there.

Other than that, I would've liked a little more detail for stats. I think I was trying to segment users by how much of the course they completed, but didn't find an easy way to do that.

I like the Teachable platform and I'll be making other courses in the future. I'll more than likely switch back to Teachable when the syntax highlighting gets done.
