This has been on my todo list for a while, as I like Simon Wardley, but I've never quite got round to using it. But I use Emacs a lot, and Emacs was the thing that sprang to mind when reading the blurb. It looks like there's this similar vibe of making custom tools easy, with there being an expectation that this is something the average user will actually do. Compare and contrast the experience of extending Emacs with, say, writing a Visual Studio Code extension. (N.B., it has not escaped my notice that Visual Studio Code is more popular...)
The GUI possibilities of Emacs are a bit limited though. Glamorous Toolkit looks better in that respect. I need to actually try it!

Something possibly similar is Studio: https://github.com/studio/studio - also Smalltalk. But seemingly dead (or at least sleeping). I encountered this via its author's RaptorJIT project, a fork of LuaJIT apparently intended to turn it into something maintainable by mere mortals: https://github.com/lukego/blog/issues/19 - some videos here: https://www.youtube.com/@lukego/streams
