I'm open to additional ideas; they're welcome.
But selecting colors in the palette first and then drag and drop
them into the Gradient panel seems a bit cumbersome.
If I could simply use "Create Gradient from Color Palette" instead.
One of my main ideas for this whole thing is actually "Create Gradient from selected Objects."
This would allow me to use larger color areas with larger objects, giving me a better impression
of the colors. Selecting colors and choosing colors in the Gradient Panel or the Color Panel is
a bit too fiddly in my eyes.
Yes, you could copy Gradient Stops via the ALT Key which is nice to have.
