Speaking personally, most of the hostile things interuptting me pose no threat. If a zombie is attacking and your melee skill 12, I would rather continue butchering, have the zombie love tap your helmet, automically stop butchering, allow you to stave in its skull, and continue butchering. 2 key strokes to solve the situation, rather than YES I want to stop, walk over to offending zombie, stave in its skull, walk back, continue butchering.
That’s why I favor removing it entirely, or at least having an option to do so.
Just making it for actively hostile rather than tracking would be an improvement though.
