Yeah, I think it started out this way partially to make this doc as simple as can be, https://atom.io/docs/v0.99.0/your-first-package

You only need to describe on window, since the package was running in the window that contained the package's code.

We just need to add one or two sentences and introduce `cmd-shift-o` for a dev mode window and it will be fine.

So let's :fire: this config and just go with dev mode 100% of the time.
