Ability to Show groups

Now with some gadgets having scope feature added to them, will be nice if we can some how know which gadges/objects are being affected with such scope.

I know scope affect groups where gadget is but groups are invisible I mean you don't really know what are the objects within that group unless you select them to see dashed line around them.

But will be nice to have a "switch" to turn on grouped objects (like shade each group with different colours), so you can add/extract a scoped gadged from them and for debugging will be great...
