uzu nodegroup pack contains:

Modifiers:
Autotools - simple shade smooth and welding
EyeOnVertex - instance an eyeball (halved) on a vertex (group or attribute)
FlowEdgev2 - Wireframe generator from unconnected vertices
FollowSurface - Used by a triangle mesh that should have a child object parented by the vertex (triangle) method. This ensures the parented object follows the surface more smoothly.
Fracture - I think it was made for lowpoly explosion (like in Starcraft Intro) when phyisics (cloth) simulation is enabled.
geouv - simple auto uvunwrap for walls, that aren't closed.
inverted_hull - simple alternative for Solidify method.
lightning - simple lightning
MapBrushCurveTool - Curve to Ground patch converter
MirrorBreaker - deletes the other side of the geometry that was marked with MirrorMarker, put right after a Mirror Modifer.
MirrorMarker - marks chosen geometry as mirrored, so MirrorBreaker can delete non-marked faces, even with a Mirror Modifer. Allows for non-symmetry while having the benefit of real time mirroring where it's needed. Put right before Mirror Modifier.
MountainGenerator - simple mountain generator with unconnected vertices.
ProximityCulling - auto deletes geometry in a radius of another mesh.
VertexLighting_Reciever - used with a Vertex Lamp attribute (Source) and shader.

NodeTools:
FaceSets (FS)
Assign - Assign selected faces to a set up to 4 (can be increased)
Clear - Clears selected faces from all face sets.
Regenerate - Face sets can be generated to the other side
