No thanks, I don't want to replace whitespace with additional visual noise.

Ended up making my VSCode show white spaces instead and setting the default clicking tab to make a single space, but I appreciate the advice to make it more visually explicit, it has definitely thrown me off before when the code i'm looking at is so deeply nested.

Do you have any other code editor visual customization tips you'd recommend for a better experience?

Great. Now get everyone else who touches your codebase to do the same.
