Damn. We've seen a lot of new editors that mimic sublime text and then fail to do some of the most baseline, important features that make it good. Atom didn't have pane resizing for over a year (and frankly, it's just too damn slow for a smooth editor experience).

I don't hate sublime. The plugin ecosystem is mature, and you're just writing python when you do write it. Is it necessarily the easiest api or easiest to test? Naw. But sublime gets most of the basics very right, and the rest is reasonable enough.
