I really wanted to like Atom. I've always felt that with the right attention, web apps can accomplish most things that native apps can.

Atom seemed promising and fast enough (I couldn't perceive any slowness), but once I started adding plugins to match the features I liked out of Sublime, I found Atom got really sluggish. I haven't tried any other electron-based editors, but I doubt it has the plugin ecosystem to compete with Sublime to VS, or any other big players.

I didn't realize how important having a responsive text-editor is, though. We expect a lot to happen with each keystroke, and we expect it all to happen before we press the next key. This is why I don't think that text editors are best done in JS.

That said, if this new text editor doesn't have features that compare with Sublime, then it isn't much better than Atom is to me.
