As an interface designer, it would be wonderful to have a "CSSEdit" or "Firebug" style live preview window w/ CSS overriddes. This would allow us to code CSS within Sublime while seeing the effects of our edits in a browser / preview window.
Although there are several apps on the Mac which already do this (Espresso, Coda, CSSEdit, etc.) there's virtually nothing on Windows which allows for this particular workflow.
