Andy, Regardless of the technical merits of the above replies, I want to make something clear.
When I use eeschema, sometimes I am making sketches to send to remote team members, and I definitely don't know the part number at that point. This is what I was doing for the original email. I was laying out a schematic with a pfet and an opamp. I knew what opamp I wanted to use, but I didn't know what pfet I wanted, because I was creating a sketch of a circuit so I could send to a collaborator. I'm not suggesting we change the public library footprints, or even make any changes to anything. I was mostly wondering if a feature I use frequently was going away.
