New version (1.1)
Accordingly with Murphy's Low when try to prove something is the moment when fail.
I've try show to a friend how it work and I've make some choices on plug-in.
Result = nothing!; nothing select; nothing hide; no errors.
After few attempts I realize I want to make actions on objects that not exist at selected level (not belong to it).
That's being said I've add few messages to inform user what's going on.
Maybe I don't cover all possible situations but You will see.
I update also on Source Forge .
