Qlikview's one of the most beautiful and hard to implement feature is Set Analysis functionality without any doubt. As long as it is implemented efficiently customer satisfaction tend to increase whilst in case of excessive and ineffective usage it is inevitable to have performance issues.
Qlikview applications can be viewed in a web application using document/iframe integration. After integration of the document an ajax tool bar appears on top of the document. Although it contains several useful controls, one might think it is space occupying and also useless. In this case you are free to hide this tool bar itself or icons on it.
