Good cross-platform frameworks for what? For web app development, you need, at a minimum, three separate programming languages but typically more, a host server, and a desktop app to render your app. That is not a "good" framework, in my opinion. And the number one thing support people ask is "have you tried it in Chrome?". Isn't that weird thing to ask? "Can you use another desktop app to verify that my app is working or not?" Web and mobile apps do not support the types of apps and functionality that I am interested in. That's fine that people are happy enough with web and mobile app development. That's also why I do not care to even address those scenarios, not to mention that they are completely different from desktop apps.
