I made some attempts, but since I'm not a primarily Clojure developer, it wasn't for me. In fact, the only things I hear about Light Table, which are all positive, are from Clojure developers. Nobody else has ever mentioned it to me let alone something positive.
If I were them, I'd double down on becoming the de-facto Clojure/Clojurescript IDE. Lots of surprise-and-delight features out of the box.
Sorry, I didn't mean that if that's how my comment came across.
What I meant was, of all the people I know that have both positive things to say and for that matter anything to say about Light Table, they've been professional Clojure developers. Therefore from my view, if I were guiding Light Table at the moment, since it has been three years, I'd really look into pleasing and making those people a very happy customer base. I would do this at the cost of other support, because in my opinion the other languages aren't being used professionally or personally with Light Table. (Perhaps they have different metrics, but if I were them, I'd double down on making a very happy set of Clojure evangelists and then re-visit support for other languages)
