Sometimes, when trying to duplicate parts of a schematic using copy/paste, I get things positioned just right and get red dots saying “Overlapping net points”.
I’ve managed to resolve this by deleting the wires and rewiring it. But it seems like there ought to be some way to be able to OK joining the net lists of the overlapping points.
Being a Windows user, the natural approach seems like right-clicking on the red dots (expecting a shortcut menu), but upverter doesn’t seem to support right-click or shortcut menus.
