I've tried really hard to like Atom. It's a shame that 'modern open-source configurable' seems to mean 'Electron app' (cf. Hyper) - I'm convinced it's not the best in terms of potential, but since that's where the collective effort, it seems unfortunately the best available.

(I revert to vim after getting fed up with Atom, I just can't help feeling that better could be achieved by forgetting legacy platforms and backwards compatibility - I'll try Kakoune if it stops being called the author's "experiment" and gets versioned releases.)
