That is super cool!
I have wanted to be able to change the root zsphere a couple of times in the past, so I am really excited you have figured out a way to do it. It will certainly open up new avenues for modelling as you have shown here, and it makes zifs much more flexible.
Bravo 
PS: All Juandelās heads are the same size (i.e. the skinning is unaffected by alternative zif arrangements), so Iām guessing he did it the old way and they are all separate models?
ha! that will make it a lot easier, Floyd!
all one zif, bonecradle 
as you will have noticed the guys - except the top one - have no necks i assume thats a result of my workaround via bmove function of zifclick: after a few even more bizarre results due to the rootzspheres location i āselectedā the node right above the root (key ādā), thereby turning upper chest, arms and head orange, copied it, selected one of the footnodes, pastedā¦ did another ādā on the pasted topheadzsphere, activated b(ranch)move and moved the pasted branch downwards and inside with a few d and i moves until it was sitting below the foot. same procedure for other foot. to get the 2nd floor guys some feet i selected everything from the top guys lower chest downwards and pasted it. oops, now its 4 legless guys as the branch included the recently pasted parts, too, of course. so i had to reload mahlikus wonderful original tool to select it from chest downwards - copy - reload the pyramid and paste four times - voila
You guys with the low member numbers are amazing!

Itās of tremendous use! Will raise the average use of space given on gaia in a way never seen before. Population will grow.
