I've integrated my recent hypertext browser into my template repository for building apps based on the Lua Carousel UI which supports making changes to apps on the phone (or computer). Now any new app built from this starting point will have a rudimentary system of online help for the entire stack: • Lua Carousel • LÖVE • Lua programming language syntax And there's tooling for authors to draw box-and-arrow diagrams in the environment and hyperlink boxes to code in the app. It's all very janky, but the combination of editing on the phone, box-and-arrow diagrams and hyperlinks everywhere seems to result in a somewhat unique programming environment worth exploring further. I'm not sure what I'll do next. Probably build some simple apps and try to build experiences for understanding their source code. This is a little bit like Literate Programming, but just a touch more graphical. LP + image maps, perhaps.
