The 4 or 5 tabs of Metro Designer
I am not a developer so I can only question. I am hoping that the certification process is rigorous to prevent malicious or amateur programming. For example, it says "Your customers must be offered an opt-in consent for any information that will be used or shared." when it gets to Microsoft is someone running the app through all of its various features and checking packets and verifying that in fact it exclusively only uses opt-in? Will Microsoft actually guarantee that all the information is exclusively opt-in, or is the certification process a simple automated check that relies on the content producer to affirm that they are not going to do anything bad in which case we won't really know until someome reports a bad app.
