With the Node Editor re-taking a center stage in Blender thanks to the addition of the ever-more-powerful Geometry Nodes, a UI update to optimize user experience was bound to take place. And the time for that update is now, with two exciting new changes: Colored overlays for noodles, and dashed lines for Geometry Nodes Fields, both of which are customizable.

The patch committed by the one and only Pablo Vazquez, incorporating code from Dalai Felinto and Juanfran Matheu, adds the colored noodles overlay and adds themeability options to Dalai Felinto's implementation of the dashed noodles for fields.
The colored noodles reflect the color of the node socket they are plugged in, offering a satisfying gradient from one color to another when an implicit conversion is being made (from a purple vector output to a yellow RGB input for example.)
The other customizability addition is the ability to control the opacity of the dashes on the field connections.
