Feature idea:
Expand the "Current options" field with an option (a toggle?) to show just the controls config, instead of the whole chart/instance config.
Rationale:
I used similar config generators for many CSS styling cases. The most popular one for me was for borders and I always appreciated when I could copy just the part I was dealing with, without a risk that something else can break. Similar here: when I deal with xAxis.reversed, I don't want to search for the right config option, and the whole config is overwhelming.
I still like the whole config idea, because if that's the starting point for me, then I need the whole config.
