Any future plans for support of modularity coloring of specifiic nodes, and/or intra-module connections?

You can use the 'color' column of the BrainNet viewer node format to set the color of the nodes. You can use the value of each edge in the edge format to set the color of the edges. The scripts below show you how to set the colors for just the edges, or a combination of edge and nodes. One script is in Pascal (which is inbuilt in Surfice but unfamiliar to many users) and the other is in Python (which requires you to have Python installed). The two languages are very similar to each other, so it is easy to translate between the two, just remember Pascal expects booleans to be true/false while Python expects 1/0:

begin
resetdefaults();
meshload('BrainMesh_ICBM152Left.mz3');
edgeload('simple.edge');
shaderxray(0.5,1);
nodesize(6, true);
edgesize(3,true);
nodehemisphere(-1);
edgecolor('actc',true);
nodethresh(0.01,4.0);
nodecolor('actc',true);
end.

import gl
gl.resetdefaults()
gl.meshload('BrainMesh_ICBM152Left.mz3')
gl.edgeload('simple.edge')
gl.shaderxray(0.5,1)
gl.nodesize(6, 0)
gl.edgesize(3,0)
gl.nodehemisphere(-1)
gl.nodethresh(0.01,4.0)
gl.nodecolor('actc',1)
gl.edgecolor('actc',1)
gl.edgethresh(0, 1)
