Hi FDP, probably the simplest way to do that is to assign the objects you want on a "visibility list" to all have the same name.

That name will then appear as an entry in the "objects" section of the scene browser and you can turn it visible/hidden with one click there.

If you want a hierarchical arrangement then groups would be how to do that. If you are having problems with groups can you send me some example files?

Maybe there is something I can fix or some tips that might help you. Like for example if you want to target one element nested inside of a group you can hold down the Ctrl key while clicking on an unselected object inside of a group and it will select that object by itself immediately instead of going into the group hierarchy.
