Default overlay interaction to none
It's annoying to manually change each overlay artboard's default interaction from 'previous artboard' to 'none'.
I found myself in many situations, where I either wanted to disable it completely, or wanted to point to a specific artboard.
As of now artboard interaction works on entire artboard, as if overlaid on each element. For interaction and review purposes, I want to mostly use an X button, or force users to use OK/Cancel buttons that I provide. In mobile situations this is more prominent. In mobile prototypes it's even more annoying because an accidental tap can close a full-screen overlay, which doesn't normally happen in mobile usage.

I strongly disagree with removing this, as it's something I use all the time. Maybe just change the default?
