One thing I would really like is a special link between nodes where they sync their settings with one another. I use a lot of tile samplers, where I do a lot of random rotation and placement and scale for natural details, and I may use a couple of tile samplers with the same settings, only different pattern inputs: one will be the color images of my pattern, and another might be the alpha mask versions of my pattern, with another being roughness or normal images of my pattern.
Creating them is no problem, because you just dupe the first tile sampler and change the pattern inputs. But if you edit values later, you have to be sure to change the same values in each sampler separately by hand, for everything to line up. Or you delete all but one, dupe the one and reconnect everything. Same goes for Splatter Circular, or any node that takes pattern inputs: I'd love a way to sync their settings. A checkbox next to every parameter that indicates that this is a parameter to sync with other nodes.
