Wish he was in charge of some of the on screen code. One of the most cringe worthy screenshots from the show: Richard using a Sony running osx writing Python in a Java file with in a variable with font
I remember reading a suggestion about proportional fonts in a discussion on HN about code editor preferences. Switched to them several years ago and never looked back.
In fact, I think proportional fonts are something every developer should try for a while, even if you end up preferring a monospaced font. In particular, if you're in the habit of using column alignment, a proportional font will quickly teach you to stop doing that and use indentation instead.
Even if I use tab key for indentation, my editor can use either spaces or tabs when saving. It's configurable.
