I am not much of a GUI user, or programmer, but I have used a lot of GUI tool kits, mostly debugging and/or extending other's work

HTML5 is the sanest for me. I can actually find where code executes, tooling using browsers (Firefox or Chromium) excellent and the declarative layout works well

The hours and hours I spent chasing the executing code in Dart/Flutter and, oh my aching head, in SwiftUI made me hate those with passion

I get that it is unsuitable for desktop programmes, for many good reasons, but it is so much better to modify.
