Those extra Buttons are homemade and it needs some code to add them to the interface.

If you want to play with the scripts (cloth) just copy the two files in your commands folder of moi.
Start MoI and hit TAB to get to the commandline and tipe in the filename without extension. For cloth it is _cloth

I'm working on something like an extension that will add extra buttons to the UI without haveing to deal with any codeing.

We will see how that goes.
