Further comments

Hey.
I know it's a draft and you might be on the correct path, but left a few comments either way, just so you don't rework too much.

It's your onboarding, so it's expected to make things the way you're used to, but I'm going to give you a few tips here and there, so you can understand our processes.

It's just small details and it shouldn't hurt your line of thought.

This refactor doesn't seem related to the goal of this PR.
It looks good, but it should've been done on a separate one.
