- Some lines return just the color codes with no content. That's to keep the padding lined up with the background highlight mechanism

- I'm keeping my main customizations in external files load in via the [TODO: Code shorthand span ] directory. They're a lot easier for me to deal with as individual files

- I'm set up to avoid saving things into the history file that start with a space, but I still don't type passwords into the command prompt. It's good practice in general but becomes pretty important when you stream to avoid accidentally flashing credentials. I call things directly from my password manager instead

- I tried using [TODO: Code shorthand span ] but didn't like it. When I would tab complete for a file it would offer different directories instead of just going into the single file in the directory I was actually in

- I had [TODO: Code shorthand span ] based of some old post but have removed it. Things seem to work fine without it in iTerm2 and tmux as far as I can tell

- I'm using [TODO: Code shorthand span ] for the background color instead of [TODO: Code shorthand span ] because the later is getting overwritten by the color them in iTerm2

- I used to have some git stuff in here, but it slows down the prompt when I'm in larger directories

- The [TODO: Code shorthand span ] and [TODO: Code shorthand span ] value both need to be the same number of digits. (i.e. either they are both 2 digits or they are both 3 digits). Otherwise, the padding to space out the background line misses one or the other
