Menu incomplete, not functional yet

Fundamentals issue, I know. I basically stuffed my modules and they're too complicated, but I'm still deadset on doing it anyway.

Whether it's a lesson in futility or not, I'll eventually find out. The coding experience.

Adding items works among other functions but it's not robust enough to be fully functional (excluding QoL enhancements, if you can call them such).

This is being tagged as a good first issue because it literally is the first issue.
