Didn’t have to try the gradient till now.
Here is my first impression.
Beside the fact that it is really welcome in Rhino, handles are hard to use.
It is even not reliable sometimes.
Color dots on gradient line (viewport) should not be coincident with themselves neither with the start and end anchors. Sometimes I can’t move the color dot to the ends or from them.
Maybe something like this could resolve this :
Stacking overlapping dots help reveal them.
Even in the panel it may be handy due to the same manipulation issue.
A list of color dots maybe handy :
I didn’t see a way to save gradient presets yet but it would be a plus.
