I thought I saw a couple recommendations against it.

For footprint viewing I usually just use PCB or the pictures
on my website. For editing I use EMACS to edit the script that
created the footprint file (all of my footprints are made with scripts).

I place all of my production footprints in one directory and run a
bash file called sch2pcb which contains the lines ---

#!/bin/bash
gsch2pcb --use-files --elements-dir /local/lan/pcb/packages $@

my footprints are in the /local/lan/pcb/packages directory.

To find a footprint by name I use dired mode in EMACS to quickly search
through the list. With the IPC7351-like names finding the appropriate
footprint is usually quite easy.

If I want to see a picture first I go to
