Make "master" deletable again / treat all copies the same

Since you asked: I reckon it’s an inconsequential annoyance, with a simple, quick & easy work-around. I’d prefer more important issues were addressed than this (for me) rather minor one … So, I’m neutral.

Yes, apparently, DxO received a lot of support questions from users who were confused about which “version” was the Master - where they did not understand that, actually, there is no true master - just different versions (as we, in this conversation, know). So, they created a "M"aster … with one positive side benefit that I explained above.
