On the topic of fonts: If your font of choice has it, try using the medium weight as the "normal" weight in your editor — I've found I prefer it to the regular weight with most fonts. I started doing this after noticing that the default Xcode font is SF Mono Medium.
I thought I was the only one doing this :P It definitely helps at smaller sizes, narrow fonts like MonoLisa simply become too faint to read easily otherwise
