I can understand your frustration and we've been there. Sure, it can still be harder to make great apps with HTML5 than native code. I'm the first to admit that. But, that is due to a lack of tools and frameworks not due to issues in the technology itself.

I'm happy that you like our app, but I admit it isn't perfect. On the other hand, how many native apps are far from perfect? We have set our mission to create the tools needed to create amazing apps with web technologies and we hope to prove that it is possible. Again, I admit that the tools aren't widely available, yet. But the underlying technology is ready in my opinion.

Consider this: How hard would it be to ship iOS 7 UI with a native app now? Why did no native developer do that, yet? Isn't it kind of telling that we were able to do it, despite the fact that a lot of people still say that HTML5 is far inferior to native programming? I'm not saying I have the only truth, I just hoping that people reconsider their prejudices and give the web a chance.
