I don't get it. If you have issues with black you have an issue with the basic Windows Phone design language. And then you can still change to the light theme.
Also, the store shows always a background connected to the current highlighted app on higher levels.
NO. I have no issue with the windows phone design language. But since windows phone is quite similar to windows rt and windows 8, the store for those two OS is far more appealing than the mess we have with windows phone. There is no reason both stores can't mirror each others looks since the OS themselves are near identical.
Hopefully that rt and windows phone merge will be sooner than later.
The store isn't a big issue for me as long as I can find my apps but the way it looks bothers me.
Also speaking of store it would be great to be able to sort the ratings by ratings or date or filter them the way you want.
