I've been using vim and emacs for decades. I was interested in a more modern editor, and I've been evaluating Atom, ST3, and others. I just licensed ST3, and in my opinion Sublime Text is the clear winner! A couple of deal breakers with Atom was that it is SLOW. Files open almost instantaneously in ST3! Then there is the issue on Windows 10 regarding focus -- If I right click on a file and select Open in Atom, Atom does not get focus. Rather, the Atom icon flashes in the task bar, and I have to click it. Bummer. I don't have that problem with it on my Mac at work, but I've been migrating to Windows 10 at home.
ST3 is highly customizable, feature rich, extensible with Python, and FAST! I'll still use vim because I administer Linux servers at work, and it is available. But all of my desktops now have ST3 installed.
I thought that instead of posting a problem or complaint, ST3 deserves some accolades!
