i explained why.   dragging and dropping "stutters" or "hitches" when it crosses the boundary of the fence.  ruins the experience.

plus, because it copy/paste works without fences.   fences intereferes and im sure its not intended behavior, just an oversight.  apps moved out of fences via whatever means shouldnt be zipped back into the fence.  

Even does it with a copy/paste.  if you want to copy something to desktop and keep it in a fence for later (for example to use the desktop copy as a disposeable, it gets zipped back into your fence and you now have 2 in your fence.....

there should simply be code with a check for if something is moved from within a fence, to outside - it stays.   i cant see of a single scenario having it function in the current fashion is beneficial.
