One note of caution, that polygon shredder can tie resources up quite heavily using the ‘INSANE’ option, to the point where my Win7 laptop became wholly unresponsive for a couple of minutes. I was using Chrome as a browser at the time.

That’s a good note. Do not go full extreme as you may regret your lack of system specs :slight_smile:

Thanks for letting me know about the promises vs eventual values article - the link is now updated.
