As far as I know the V6 “Isolate” command does not take in account locked objects, thus the object you may want to isolate can be surrounded by a bunch of locked other objects, when those objects are walls or floors: this is not especially handy
Isolate and/with “do not show locked objects” would be perfect. The selection would be truly isolated.
Hello - added to the pile, thanks.
A YEAR after, this wish is not yet raised up. :\
