Wow, this looks like a great combination of best parts of the writing tools I've been using, from Storybook back in the day (now open sourced oStorybook) to Scrivener.

I'm currently using Scrivener together with Aeon Timeline. This looks like a great program to tie everything together.

Is the single lifetime license just a launch promotion? I'm wondering as you might need to bolster the revenue model a bit to sustain development.

Great job though, looking forward to seeing it!
