Orient Yourself Course Update

The Orient Yourself course has several problems. It does not have clear instructions on how to operate the controls for moving and looking around the 3D environment. Some instructions near the end of the course tell the user to place blocks on the x, y, and z axes. However, there are no lines drawn on the grid to represent those axes. When I scroll down on a slide of notes and move to the next slide, the scroll is already scrolled down instead of starting at the top. The course is not easily accessible on the website.

I want to add the controls for moving and looking around in the course and add dotted lines in the environment to represent the x, y, and z axes. I also want the scroll of the next slide to always start at the top instead of staying where it left off. It would be helpful to new users if the course appeared on the welcome screen so its easier to access.

An alternate solution would be to scrap the orient yourself course and start from scratch, but I think the course already has a good foundation and we only need to build on top of it.
