Kate, thanks for the reply, but I would only consider the full vector side of Designer Pro. The Photo stuff doesn't interest me.
I also don't want downloadable content, it's effects-laden and of no interest. I am also cheesed off with the load time of Designer Pro, it is much slower these days.
As Steve says, 64 bit is essential as are PDF/X output.
There are a huge number of Vector items that could do with refreshing, too:-

The Bitmap Tracer needs a complete overhaul.

We should be able to save a user-adjusted interface and not have to go through the rigmarole of readjusting the Control Bars/Button Palette. That should only ever be a one-time operation.

Far better Open Type feature implementation. The current version is extremely clunky, invoving a lot of guesswork.

The 3D Tool, whilst feature-rich is very much rooted in turn-of-the-century design. One can tell which software was used to produce the results ~ eye candy.

On the subject of eye candy, the downloadable content is just that. Unusable for me.

One would hope with a stripped down vector based program without web/photo content that the program would load a lot faster, too.

Just my 2 cents.
Bob.
