Hi Michael , I use isolate all the time, very helpful command.
So what I am looking for could be described as a negative isolate fuctionality.

If I hide one object with the default "hide" and try to mae it visible again, it
diplays ALL hidden objects which is not helpful when I want to keep my
scene as before just adding teh previously hidden object. It get specially
confusing when there is a huge number of hidden objects which suddenly
get displayed at once.
