Custom normals for Duplicate along edges node

[Durman]

There is interesting use-case of generating walls with the node which requires more accurate control over edge normals. It would be nice if the node could take extra input for edge normals. It's seen on the video that some windows look inside a building and some outside.

One more improvement could be adding extra output of a mapping between output matrixes and indexes of input edges. This data would help to build different walls from different blocks.

Did you try to use Vector Sort "by connect" before adaptative edges?

The node does not consider input edges as curves or polylines. Input edges can be connected any way with each other for the algorithm it does not matter. Probably if the node could understand that input is curves/polylines it would be the solution but to have input for custom normals should be more flexible.
