I have 2 requests but they are pretty big ones 1. Full Device api / OS integration, basically phonegap supported natively in browsers, some support is slowly trickling though, I never understood why its taking such a long time though 2. Fix whatever performance problems make building RIA really damn hard. Some people say this problem is inherent to javascript + dom and cant be fixed, I am not sure, I do know browsers were making amazing steps over the last year or 2 and have mitigated it a lot, but its not quite there, in particular GC stalls are incredibly hard to work around.
