Quick update to the instructions to explain how to add this in v20. Like the v19 update, nothing about the code has changed, just where you're putting it. Because of this, I've just written the instructions for v20 and noted where things are different for prior versions, but if it's too jumbled up with all the "for x version do y", I might begin splitting it up.
This script is technically already perfectly compatible with v19, it's just the way that I made it plug-and-play isn't compatible with v19. So I've changed it to be step-by-step instructions for how to put it in rather than a plug-and-play script, because:
It feels cleaner to me to just put in a few lines rather than re-define several large sections for a minor change
Since the steps are the same, I only need one section for v18 and v19 (plus it'll make it easier to test for compatibility with earlier version)
It's easier to check for conflicting plugins this way
v18 plug-and-play will still be up, and I might eventually bite the bullet and write a plug-and-play for v19.
