To manage mental mapping of what is being drawn, I keep methods that create widget trees short. My rule of thumb is that whole method has to comfortably fit the screen at once. For each section of the main tree I create a static function that returns a branch of the tree. These functions have descriptive names that help you visualize what element each function builds. If a tree inside a function is long, it is broken down in the same way. There are some fluent extensions (for Xamarin.Forms and probably future MAUI) that help you build UI in declarative fashion with C#. Same extensions could be created for other frameworks. https://devblogs.microsoft.com/xamarin/c-sharp-markup-for-xamarin-forms/ https://devblogs.microsoft.com/xamarin/c-sharp-markup-for-xa... https://github.com/VincentH-Net/CSharpForMarkup https://github.com/VincentH-Net/CSharpForMarkup For reusable custom widgets that can't be done with a static function, I create new classes with their own widget trees. Try to keep widgets composable and avoid inheritance if possible. Hot reload is coming in .NET 6, so waiting for rebuild will soon be history. I have no experience with QML so I can't really comment on that.
