I tried to copy e.g. an Link from Chrome App to the Folder on the Desktop. This doesn't work for me. I think this is a problem between Apps and Desktop Applications in general. The same problem occurs if I choose the Mouse to Drag the Link on my Desktop. This doesn't work too if I starting Google Chrome as App instead of Application on the Desktop I cannot move to the Desktop anymore This happens with other Applications too.

I think this is a very important issue to interchange between Apps and Desktop Application.
