Change visibility for multiple items at once - by dragging (like in PS, AE…)

It's not a killing feature blocking my workflow right now, but it's another great timesaver if you have a lot of stuff in the project.
It's seems probably more complicated from the UI, because you would be changing visibility of skeletons & bones & attachments & skin placeholders etc at once.... but I think it would work fine.
The same like it works with folders in PS.
Moreover, user can select what he wants to see in the tree (the buttons on the top of the Tree).
