True, true. Not sure I could manage without it either now!
That said, I must admit I'm particularly fond of the Popout facility when running a test game (which opens a new instance of the game running in a separate window). It's useful for stuff like comparing conditional narrative, but mostly I just love the ability to Popout and test one option, then close it and Popout again to test the next option, and so forth, before advancing the main game instance to the next major *choice, then repeat again to Popout-test each option. All without having to restart or use any sort of testing code… Sheer bliss!
