I did discover that I needed to add a comma. YAY! I learned something. But the ignored_packages was added to the user settings, even though it was already in the default. Since the user settings works in much the same as CSS (which I do speak), anything different in the user settings overrides the default settings, which is why it’s a much shorter file. However - THAT’S not the tutorial’s fault. Except the tutorial doesn’t show the “Vintage” or explain what’s going on at all.
Happily, the extra code block was removed from the user settings of Sublime 3, AND I figured out about the comma.
Also, you might want to mention that because of “rootless” in El Capitan (Apple and SIP - bless their hearts), it’s not possible to go in through Automator (lesson 2.2) and create a shell for the shortcut to /bin/zsh/ so one can right-click on a file to open it in Sublime. Because rootless won’t let you access /bin/ (among others) any longer unless you turn off SIP. I’ve been told there are work-arounds, but definitely not via Automator.
