So most (all) gradients are even transitions along a 1d line. AD does 2d, so why not 2d gradients. This is in two parts.
One) every gradient would have a "Distort Mode", distort mode brings up a grid of handles, rotated to the direction of the gradient and radial etc. for the respective gradient. These can be moved, distorting the gradient. This would be basically a special implementation of the second part;
2D gradients) each 2d gradient would be a assortment of points, each with controllable spread, hsl, and shape.
Spread is the distance, think a gaussian function, squished or squashed. HSL is obvious, color controllable with any of the already implemented options. Shape is the shape (no duh), by default a circle, but a star (long points extending from a circle), square, ellipse, or custom could be chosen.
Inspired by Logoist 2's lightmap feature (also a good idea to implement), blurred stuff, low-poly stuff.
