Is there a way to make them work in the older versions?
From which version to which have you tried? I have never tried so I can check that out.
Alternatively, Cassel, could you do a script to quickly fill several documents with different gradients? Or is there one already that might work for it? Then I could at least share .JPG overlays.
Could you clarify what you mean? would it be to display them like a set of papers placed side by side, or making individual pages, each with a single different gradient? My guess is that either one would be possible, but I would need to know a bit better what is the end result and such.
