Features that Expression has that Xara should have

[Xhris]

what was needed was a 'de-rasterizer' that will produce output USABLE in a vector drawing program to facilitate the exchange of data (images) between bitmap and vector based imaging apps.

I've been thinking of this very feature for years now. But I would be surprised if it would happen anytime soon.

It's arguable that the Xara tracer could do with a revamp, but I suspect that isn't high on the list of priorities.
