I had an issue with this mod yesterday. It seems if you install it when you already have ship a space using stack separators attached attached radially (I used radial attachment nodes), the mod changes them to Horizontal Separation Manifolds. That would be fine, except the ship blows up if I engage them! I tried remove the mod, but it completely broke the ship (no parts function - the inline command module detached and floated away). I did not try to build any new ships with the mod and test those. This was just on one existing ship. My other ships without stack separators were fine.

Have you considered using the node target or the navball ascent guidance to determine deviation? That would be useful in manual flight and also sync your mod very well with the MechJeb autopilot. I'm interested in using the mod as a safeguard against fuel imbalances and engines cutting out asymmetrically. I think it might also be useful to do asymmetric staging. I haven't had much luck using it in that way yet.
