Thanks, I didn't know the name of this feature! gschem also has that "connect by kissing" feature, probably under some other name. During my ~15 years of gschem usage I found it a bit less annoying than the smeared wire mess moving a connected symbol usually caused. But I am not sure it was useful or annoying in more than 50% of the cases. Btw, this is not a different feature in sch-rnd terms: when a terminal is connected to a net or another terminal, we have an explicit connection object created. Implementing either the "connect by kissing" or "symbol keeps connections on move" would be the same piece of code: when moving an object away, look at connections broken, and draw wires to preserve them. For now I think we can (and should) live without that in sch-rnd. It's really not that hard (or inefficient) to draw a piece of wire. Best regards, Igor2
