There are occasions when you want to move part of a drawing that has not been grouped but without it affecting other connected geometry. So what do you do? What I often do is use Move/Copy and then delete the old instance. But that is often a bit of a faff.
What about having an option to Move/Delete? Either by using a control key or by right clicking after the move, you can choose to delete the original of what you have moved. It would have to be clever enough to realize that you rarely want to delete the lines that connected the original geometry to the moved part so that you don’t end up deleting far too much of the original. Not beyond the wit of man (or developer), I would think.
Perhaps this facility already exists somewhere?
