Essential plugin for me. Prior to VaM 1.2, this was the most comprehensive way of comfortably storing/loading atoms at positions & orientations relative to bodynodes - mostly because VaM's 'save preset' options didn't offer more than rudimentary functionality for some atom types. Still not sure that the new SubScene atom will replace CUAM for me.
I also like the thoughtful way the GUI is set up wrt handling linked atom's storables.
One thing I'd very much like to see in (possible) future CUAM versions is the ability to store/reload groups of atoms (i.e. a parent atom with its children), with the parent atom's position & orientation relative to the bodynode it is linked to determining the position & orientation of the other atoms in the group. This would be particularly usefull for animation patterns and their associated animation steps.
