This looks very interesting, though the installer tells me that it is an unsigned executable, meaning Windows doesn't like to install it. Can you fix that? Using InnoSetup for instance?
Also, as it stands your application (built with AI) has some major flaws (Locations for instance). The UI is far from intuitive for now. It has very good ideas behind it, especially as you are a Ren'Py developer, but it is having some drawbacks in the flow (or lack thereof).
With the above critique, do build on, it is a good tool idea.
