You've mentioned the impetus for the change was driven by the old site's backend being an arcane mess, which I can understand, but that means that you can't call it a day with the current site iteration. I'm expecting a lot of changes and features from the old site to return in the coming months.
Unrelated, I would have made a comment about how horribly situational a new feature like the "Copy Notes" option is, but I have already made use of and benefited from the function today. Seriously, what are the odds?
