Have an option to "run in background"

I have two machines, a fast one for work, and a slower one for side projects. I relied on Crimson Editor before coming across Sublime Text. It had some good features, but best of all it opened almost instantly. Trying to keep a clean taskbar, I only keep open the applications I'm actively using. Speed is important when opening new code files so that flow isn't disrupted.

Could there be an option to run Sublime Text in the background so that opening files is lightning-fast? Chrome does this to keep the browser feeling fast and it's a wonderful experience. It also has a "run in background on startup" option so it feels extremely responsive from the first "run".
