Nice to hear about updates!
I had a note to say about a small thing that happened with me and bitsy. I've been using for a long while and I got used to only using the coding screen for dialogue. This later made it so that I forgot how to use the regular dialogue menu and could not explain it to newcomers of bitsy. I wonder if there was some sort of way to merge the dialogue "coding" to a single system usable by both newcomers and coders that is easy to use and understand.
For example in the game making engine Stencyl they have a code block system that makes it easier for newbies to code by making it easier to visually see it in terms of these blocks that snap together. They also have a customizable blocks, so coders can write their own blocks. Those, I think, are also something easy that newcomers can import and understand how to use. They just copy in code into the customizable code block, then they insert that code block as they would any other code block piece.
It would be nice if bitsy could have a basic system, but also more advanced coding done in a way that was also accessible to newcomers. But maybe that is what your module system is aiming to do already?
