First, I worked a bit more on my observer system under the hood. Instead of relying on observer objects, the subject just takes a reference to a callback which is intended to be called on the subject’s notify(). The picture is a demo where anytime I press a key it prints “test.”

I also went through my code and tried to leave comments which clarify the functions and usage of certain things, which should help to make it more usable.

Also, my Git connection keeps breaking, which is enraging!
