I believe I brought up a similar idea years ago. Many of us have multiple systems, which usually get cluttered together in the system specs dropdown or even spill over into our sigs. Upgrading the system specs tab in such a way would be a a pretty neat way to list a bunch of rigs, if one were so inclined, and it wouldn't be cluttery.
That said, I think this thread has generated a disproportionate amount of drama... I understand W1zzard is busy, but I also see no one forcing him to do anything, or being mad if it doesn't get done. This subforum literally says "feature requests" are part of what this section is for! So here's a feature request. If it happens, great! If not, that's fine too. No one is going to fall to pieces over it.
