Thank you for your review.
Actually there is no duplication, it is only the Actual name, and the Twitter Username, in our case for example, the actual name is Optimized Sense, while the Username: OptimizedSense.
Secondly, this is from the default Twitter API that we currently use, and we are working currently on some modifications on the twitter API so it can be customized according to your suggestion (to hide the header and footer).
Keep tuned with the next version.
Optimized Sense Team.
