Don’t get me wrong, I’m not saying this isn’t important to you, but seeing how busy the core team is right now with the move to React and what not, I wouldn’t expect this feature to be prioritized anytime soon. But if you implement it and open a pull request, you’re much more likely to have this feature added very soon.
This is the whole point of Atom being open source; you see some feature that is missing, you should open an issue/feature request for it. And then ideally, you implement the feature yourself and open a pull request.
None of us are in any position to demand anything from the core Atom team (nor any other open source project), so if we desire some feature that is missing, it is our responsibility to help implement it. That’s the “manifesto” I try to follow at least.
