Well we seem to have had pretty much everything else! I thought this could be useful for people to see what extensions people have installed and maybe unearth a little gem or two. No obviously everyone will have the same standard System Preferences so if we could keep it to the 'other' section it will make life easier. Anyway, mine: Pretty basic really. The only 'unusual' thing maybe Flip, I use that with my Belkin KVM when I am at my desk and want to share keyboard and mouse with my Mac Pro. I will post my Mac Pro window in the morning, thats a bit more interesting!
