Hello Dear Geoff,
I really appreciate your efforts and times on this wonderful work.
Btw, how do I get the result “Electrostatic Potential”? It(version 1.2) says the function is not supported yet.
Also I tried to find the submenu (Extensions–> Create Surfaces) from the version 2.0, but it looks like that it does not have the submenu yet.
Thank you so much for your help!
