Trying this out at the moment. Aligning verts works fine and as expected but it looks like when doing alignment to face or edge, if you select a face or edge and multiple verts, it keeps asking you to select an edge. If you just select an edge/face and a single vertice it works OK. I may be not be using it properly though. For me, the vert alignment option is worth the installation, better than other systems I've tried.
