Presets: "feature" or bug?

Andreas: Thank you for the unexpected help. Yes, as I had on several occasions updated with a full refresh to an updated OS, then manually ported over items from a saved BTT subfolder. The Default duplication -- which seems so obvious now as I absorb your input -- had baffled me. Fortunately, the screen colors of each "Default" do differ, so I was manually able to shut down the Impersonator as I duplicated in the original preset those commands of mauve, not black, coloration.
Please allow me to acknowledge as well the goodwill, good nature and intelligence inherent both in BTT and, by direct inference, in you. Your coding and the humane way in which you continue to offer BTT to the world has allowed me to know you to be a good man of encompassing creativity.
Very best, Michael
