Although I never got deeply into the field, I think the UI builders also had the problem that web frameworks do: which is though they make it easy to do the easy stuff, they eventually make everything harder. That isn't supposed matter because most real-world customers only have simple needs, so you want to bang out the apps quickly. But in practice I have never seen a use case that was really as simple as it was supposed to be -- they all end up in the "too hard for the framework" bucket.
