This hiding sort of defeats the use of quick battle as a testing tool I'm afraid.
And heaping another setting to disable the hiding setting for the purposes of testing (ha, try to define when it's testing and when it's not...) on top of everything, well, it just complicates things more, not less.

Entirely possible that QB UI gets too cluttered. But I think something other has to be done, not crippling it.
