Hi Nullart, thanks for the suggestion, but wow, that was a crazy ride. I thought "This is a great idea, and should be trivial, how hard can it be, right?" and decided to slip it into the upcoming release which is in testing phase at present. How wrong I was... many hours later, having ripped out a bunch of really old Interface Builder code and replaced it with many iterations of SwiftUI code, it works. This will be included in the upcoming release.
