If I remember correctly, the old (ver 5.x) ipe manual had a nice 
explanation about multiplicity of vertices, which does not seem to have 
made it to the new manual.  Am I mistaken? Is it still there? Or was it 
never there, and I completely hallucinated the whole thing?

Is there a way to change a multiplicity of a control point during 
editing? If not, snapping to control points would provide one.

Me too, on the other hand, as long as you keep Ctrl+E, do whatever you 
want with double click.  I dislike double clicks and simply will not use 
it. If it makes people happy ans is not hard to implement...
