Isolate Selection with "Layers".. Bind LI_Isolate to "Alt+Q" and LI_Back to "Q" or whatever suits you best. Has its limits compared to the original, deleting or attaching objects will result in everything beeing unhided.

I got tired of having to animate my bones by hand when I'm skinning a model, so I made this script. It will add an animation to ALL selected objects, rotating in sequence one at a time. Now you can skip the animation range creating stage and skip right to skinning. Yay!
