Description

This is a small tweak, personally, I find single-character variable names like these to be less than ideal. IMO no reason to not change these. 🤠

@jacobherrington I completely agree, thank you 👍

@spaghetticode There are a bunch of these throughout the codebase. I might go in and do a more sweeping change in the future, but it would also make a good first-time contribution for anyone new to open source 😉

@jacobherrington I think that's a great idea! I will open an issue and mark it as beginner-friendly
