Immature, obviously. Far fewer person-hours of labor have been put in relative to what you use all the time. But I find it worthwhile to get off the constant treadmill of new versions with features I don't care about. Cutting down on complexity there creates headroom for me or you to try out new approaches I or you might care more about.

My most common development environments these days:

* A live-programming infinite surface of definitions that works well on a big screen: https://git.sr.ht/~akkartik/driver.love Has minimal syntax highlighting for just Lua comments and strings.

* An environment that lets me add hyperlinks, graphics and box-and-arrow diagrams in addition to code. Also works on mobile devices. Examples: https://akkartik.itch.io/sokoban, https://akkartik.name/post/2025-03-08-devlog, https://akkartik.name/post/2025-05-12-devlog

The second set of apps are built using the first approach.
