I've been slowly working on a new UI toolkit designed to provide first class mruby support, provide linear programming constraints for layout, use openGL rendering via nanovg, and use a variant of qml (dsl using reactive properties) for widget definitions. Qt was nice for some initial prototyping, but given the scope of some user interfaces that I'm developing a new toolkit seemed justifiable. The old pain points mainly included ease of scripting, performance, and easier custom widget definitions (mainly for data visualization).
