Being able to resize the gradient editor, specifically horizontally, increases the accuracy of color node placement.
That’s all. Thanks. Be well. (or else)
EDIT: Perhaps also being able to set transparency per color node? That’s always a fun option that can achieve some darn cool effects.
There’s a separate Alpha (transparency) gradient, so we won’t add transparency to the color nodes. It might be a lot more useful if both gradients were in the same editor though.
The gradient defines the color of the particle over its life, so I’m not sure what “radial” would mean? (The gradient is not applied to the particle spatially, just temporally).
