I repeat the same thing every time there's an Atom discussion because it's a a deal breaker: While Atom is slower, that's manageable. I have a MBP with a Thunderbolt display, and typically have 2 or more full-screen editing windows going at a time that I swipe between on the large screen. Atom often loses track of these, putting modals on the wrong one, but causing it to go away when you swipe to the instance where it is. As a result, the modal blocks, and often is something like a Save As. Forcing me to hard-kill and potentially lose work is unacceptable. I've been using it for about six months, upgrading often, because I really do want it to succeed, but at the end of the day, I'm a developer with work to get done.
