I do occasionally use the Ghost share plug, so it’s great to hear this type of “export” will eventually work as well.
For library distribution, I like the ideas from @janssen-io 's 🔌 External Libraries plug. Having a full github (or other) repo is a bit nicer if you want to have issues and an easier history. Gists would definitely be nice for quickly sharing something though.
Looking at Library/Std/Gist - It really reminds me of literate programming. I guess space script was already kind of the same way, but it’s still pretty neat.
