I love the edit markers in the last screenshot. But too skeptical about the performance of a text editor running in webkit. All of my experiences writing text online have been bad. So the jump into using webkit for an entire dev environment fills me with dread.
Brackets[1] is a decent programmer's text editor developed by Adobe and using WebKit. It works fine. The performance and polish of web editor components like CodeMirror has come on a long way in the past couple of years.
Have you used LightTable? It's quite fast as the editor. I'm sure Atom is similarly fast. It doesn't run in the browser; it just uses WebKit as the engine.
The nice thing about Vim mode is that it glosses over latency by making simple edits take fewer keystrokes. It's sort of why vi was invented.
In the words of Bill Joy himself:
> ... you've got to remember that I was trying to make it usable over a 300 baud modem. That's also the reason you have all these funny commands. It just barely worked to use a screen editor over a modem. It was just barely fast enough. A 1200 baud modem was an upgrade. 1200 baud now is pretty slow.
> 9600 baud is faster than you can read. 1200 baud is way
slower. So the editor was optimized so that you could edit
and feel productive when it was painting slower than you
could think. Now that computers are so much faster than you
can think, nobody understands this anymore.
Yeah, as the create of GitGutter for ST, my first thought was, cool if I switch to this I can write GitGutter in CoffeeScript. Then I thought, being Github, they would probably bake that in.
To put "often" in context, I raised a Github issue on it today which was resolved within a few hours, it's improving incredibly quickly (and it's already awesome).
I thought CodeBox was using the ACE editor as part of their system like Cloud9. And I believe Orion and Codenvy (my company) use CodeMirror. Looking forward to trying out Atom. I can see many advantages already of it as an editor.
