Analyze code, write pseudo-code, then refactor project

## Description

I wanted to see the flow of my functions and event listeners so I added `console.log` statement in every function and listener, and for some I added `console.trace`. That showed me when every function runs based on 19 different user actions on the home page and 27 user actions on the board page.

I found errors and mistakes just by doing that. I am now writing pseudo-code retroactively and it is showing me where I have repetitive code and where I need to refactor.

I am going to write pseudo-code for all user actions then refactor the entire project.

## Type of Issue

- [x] Refactor / cleanup
