Just a quick note on this Pen Editor UI/UX change. The Save button used to be only that. You click it, the Pen saves. It’s only other job is a little line on the top of it to let you know when the Pen has unsaved changes. We’ve updated it to have a little dropdown menu to give you easier access to a variety of other functions relevant to any Pen:
If you ask me, Format Code on Save is under-utilized (as it’s not a default), and it’s such a pleasure to use. I’m sure most of y’all have autoformatting going on in your local editor using something like Prettier, which is exactly what we use. Give it a try!
