Every web app of significance has a load to distribute. Some wait until some resource is needed to load it and other prefer loading all up front. I am the latter, simply because the user expects a wait time at the beginning, only to enjoy instantaneous gratification throughout your program's use.

I do this by loading every window into hidden divs and showing them through JQuery's ,show/.hide
I set up the states for each scenario throughout the App. Then I put these as functions in their own .js file and call whichever I need to turn on and off the sets of divs as needed.
