How we use a shared configuration file for Spacemacs and managed to add personal configurations on each machine too.

Sublime Text 2 has been my editor of choice for about a year now. It's a great piece of software, but gradually I've been adding my own config options to make it just that little bit nicer for working with on a daily basis. I like it, and the guys in the office like it enough that it's the default config on our pairing machines at the moment.
