Joel Spolsky wants more web-app-developer friendly features in the web browser:

"In the previous rounds of HTML enhancement, the world's great graphic designers (like Jeffrey Zeldman) made the most noise and got us things like CSS which allow the kind of pixel-perfect page layout that the marketing people like, done in an intelligent way that separates content from presentation. Kudos. They got what they wanted, mostly, and quieted down. Now it's time for us application developers to start clamoring for the features we need to develop great web applications. Here are some examples of the kinds of features I'd like to see in web browsers."
