As a generalization of D16227, it might be helpful to have a "Select Similar" node.

The node could look like this:
{F13984482 size=full}

The selection input is the initial selection to start from.
The "Value" field input is used to find which areas are similar.
The selection output is true wherever the value field matched any of the values in the input selection.

Open questions:

Does this generalize to other "Value" data types?
If so, should we try to avoid replicating all the options of the compare node here?
If not, is the node still useful enough?

I think it makes sense to give more control over the product of the group sets so that we can multiply a random island group by the island number to get a unique group ID in the island space.

py mocup

connectMap = {}
for edge in mesh.edges:
    vertices = edge.vertices
    if vertices[0] not in connectMap:
        connectMap[vertices[0]] = [vertices[1]]
    else:
        connectMap[vertices[0]].append(vertices[1])

    if vertices[1] not in connectMap:
        connectMap[vertices[1]] = [ vertices[0] ]
    else:
        connectMap[vertices[1].append(vertices[0])

I use connection maps like this for A* and for other stuff
to store what vertex are connected by an edge, or what faces are connected to a face with an edge too.

this would be used with a input index to then select the vertex
(I can't code c++ that well yet to help there)
