Preflight checklist

Problem Description

I started using Screenbox, and they turned the navigation buttons transparent and it looks so sick

Proposed Solution

Add an optional toggle to turn the navigation bar and windows buttons transparent. I believe it looks very good, but I also recognize that not everyone likes it and some people need a 100% opacity for disability.

On a second thought the nav bar is fine, if it was to be turned transparent it would look bad or cut into the anime.

I also used kita for the meme, but here's Charlie for an actual picture
