I recently had another idea when someone was talking about MNG export.
It should be possible to create an instance of a layer and use it
somewhere else. This is especially useful for animations - I imagine a
tree of layers. The first level defines the frames. So, the same layer
(say, some background) could be used in every frame and the MNG exporter
could exploit that fact and create nice, small files.

Apart from that, one often needs a copy of a layer to create some
effect. Combined with effect or active layers, one would only need to
alter the source layer and everything else would change by itself.
