Ok, kind of a simple idea but having a level of detail control for Previewing from file would be a huge help when placing proxy objects like trees. I have found that once trees are converted to proxies the trunck of the tree dissapears making it almost impossible to place accurately.
Another proxy wish - the ability to inherit the origin point from the original mesh.
maybe you can work in coordinates (x,y,z) and with a specific gizmo that you hav defined…so you will be able to control your proxies…
btw i don’t know if a proxy keep in mind the gizmo location.. :?
