I think it might be a good idea if the behavior of both the older reroute node and the newer circular ‘point’ reroute node (if you could consider it one, that is) were adjusted a bit, with regards to how the angles on where the links (or noodles, in Blender terms) connect to the node. Basically, I think the way Blender handles the reroutes in its shader & geometry editors makes a bit more sense than how ComfyUI does it.
It would make for neater workflows if the rerouting allowed for arbitrary angles that matched the direction of the links without the weird zig-zag effect (with the linear link style), or excessively curvy splines in spline mode. Even with Blender’s spline noodles, it is still possible to create reroute points that allow for precise 90 degree turns, etc, allowing for neater node setups.
Also, it would be nice if you could adjust the size of the circular reroute nodes. In any case, I don’t think taking inspiration from Blender’s design philosophy would be a bad idea.
