thanks, it only gets better ;-) i can't take any of the credits for the good
looks.. the css wizards at plone.org handled that.

that would be perfect! i guess this will be using the new repos uuids..

in case its of interest to anyone i'm attaching the code i just finished which
returns a map of rev numbers to repo paths given a node (the pic above was a
setup, no copies involved). its not very pretty nor perhaps useful ;-), other
than looking at the algorithm.. it works ok for the minimal test cases i
gave it.

thanks guys,
