Thank you for the source, I will add Custom AutoISO to my upcoming private release.
But I'm not able to add it to the trunk. I have been blamed by AllBest to change "his" trunk code.
Obviously, there are territorial claims and invisible border lines, but no-one talks about.
I asked in the forum: What are the rules? - no reply.
I'm not willing to work out the rules the hard way, by trial and error/punishment. Sorry.
