How can anyone build a serious front-end without proper keyboard support? Every single one of these new-fangled web UI kits is missing this important feature and if you're going to do it at all, it really does need to be a core consideration. This is my biggest complaint about most web apps and the number one reason that I think web apps are perceived to be less powerful. Give me a break web devs! (Or, should I say browser makers?) Let's get serious already!! (Also if we're talking browser manufacturers, I'd really, really like to see a completely separate abstraction for apps than documents. C'mon man!! We've been inventing the same thing for 20 years, let's get it right for once :)
