My brain perceives `fun doSomething` and `fun do Something` very differently, so I'm assuming you have a very good reason on why that's the case.
So I added the left padding to uppercase letters, and to avoid confusing it with a real space char, I made the space 4x wider.
I kept experimenting with the real space width and the padding ratio. At first I added like 1/6 of padding, and I noticed it took me just a few minutes to get used to it, so I increased it to 1/3.
It also depends on the font size. if it’s over 18pt then 1/3 of padding is too much, but I think it works well for 12-14pt
So if I’m sharing my screen with a large font I change it to mono.
