Downloaded apps when opened shouldn't direct you to a home website.
I downloaded the gold app brought to us by a third party for the playbook It shows a static price chart of gold, silver and platinum. Their web address was at the top of the page. I tried to pinch to zoom on the chart and it opened up the browser and put me into their gold trading homepage. I think this kind of app should be banned from the playbook. Offer something to make the playbook a better experience for all, not a tool for other companies to build a window app, then if touched anywhere on the screen it takes you to their website. It is like cheap flash advertising on web pages from the internet.
