I didn’t know about the catalog either- that’s really cool! I’m actually have a similar feature upcoming for the elm-lang.org editor, so you will be able to save your own code, see other peoples work etc. For that reason, I think it may make more sense to link to the catalog from Ellie itself as you suggested, too. I do however see how it’d be helpful to have more examples for the JSON decoder/encoder readily available, so I think I’ll add some examples on the site/docs. Thanks for bringing this up! (+ thanks for answering questions on the elm slack! )
