Yes, your editor needs to support elastic tabstops. http://nickgravgaard.com/elastic-tabstops/ http://nickgravgaard.com/elastic-tabstops/ The main reason why I stopped using a non-monospace font is that elastic tabstops are not available everywhere and thus no real codebase uses it. I minor second reason is that I did not find a coding-focused non-monospace font. For code you have to clearly distinguish I and l and 1, O and 0, etc. Nobody optimizes non-monospace fonts for that. It seems that there is now at least one such font: http://input.fontbureau.com/info/ http://input.fontbureau.com/info/
