I’d like to see something about automated testing; the most important being “what things/how much do you test in your Elm projects”, and if there’s room for two questions, maybe also “what tools do you use for testing your Elm projects”.
I think another useful question would be what tooling do you when developing your elm projects, with checkboxes to select from elm-test, elm-reactor, elm-server, elm-brunch, webpack, etc.
