My usual freelancer has disappeared so I am looking for his replacement and possibly a long term relationship. :) The panel has a tree structure with nodes. Every node is basically an object with fields, which you can edit on the right side of the screen. Small Changes: *Not make the whole tree refresh every time you save a node. *For some user, some nodes do not display on the right (loads perpetually) *Add a few fields to a couple of objects.
