I am working on the global navigation design for web applications for IT users. The current behavior of navigation structure is like Classic Yahoo Mail in which navigation, tools, buttons are scrolled with the content as the users scroll the browser's scrolling bar. I consider the design pattern like the New Mail Yahoo where users only scroll the content or workspace. Navigation, buttons and tools are in fix location. So it works more like desktop application.
Do you know books, research or any other resource that I can look into about this topic, pros and cons?
