Background:

if globalVars.appArgs.secure:
       return

This copy-paste code is all over the place. I propose an @secure decorator in NVDA that can help ensure NVDA never runs on secure screens in a decorated method.

@secure
def save(self:
   blahBlahBlah
)

Advantages: @secure could be updated in the future if new security related things are added. This would prevent shot gun surgery from needing to be performed with said feature being added. Addons could use this by default.
