Mattias, thank you for making this neat (and FREE) tool for us to tinker with. I have been enjoying it so far. I have a little feature request if you've got the time and inclination.
Right now, when you move from one dialog section to another, the whole screen fades out then fades back in. I personally find this distracting, especially when you're just giving the player a series of narration text (like in the tutorial: about_items, about_items2, about_items3).
Could we get a global variable to control the speed of the transition fade effect? Or if it's simpler, maybe just a toggle to disable it? The idea is that the screen would refresh instantly when the player clicks through.
