Ah on this topic I dont know if we mentioned it in Vienna when you were
gathering requirements, but one thing I *often* get asked by users is why
when adding new layers (multiple at once) QGIS does not add them in
'natural z-order' with polygons below then lines in the middle, then points
above. Is this something you could do? I believe sorting should only apply
to the added layers (so adding the sorted layer above the current layer
rather than above the last layer of their geometry type). Though no doubt
somebody will think just the opposite....:-)
