For a long time, I've been symlinking my Sublime Text configuration from Dropbox to where it wants it. Last night, I wiped my computer and remembered how handy this is.
Someone on Twitter suggested that I put it in git instead. Definitely a much better idea. Here's my Sublime Text configuration. It just adds packages I've installed that aren't the default, my theme, and of course all of my preferences.
Hopefully you find it useful.
