We were going to try to review this to see if we could use it for a new project, but we can't due to missing a key element, which is a progress indicator. For example, imagine if you're building something to allow a process or upload that takes a longer period of time than a normal page load. This element would have a visual indication that helps end users to know how far along the process is and when it might end. I guess the DNN installer does this too. :)
