i thought i'd add a couple more Mac software bits that have come in handy this past fortnight. My iTunes collection has been bulging at over 12 Gb, and i keep having to shift it around in order to do video stuff. so i've been delighted to find a way to make multiple (hence smaller) itunes libraries using Libra. (i know, but that's what they called it). it's shareware. and there's a PC version. (having an iPod would certainly help)
the second thing was that in trying to get Final Cut Studio to fit on my Mac, I've had to play around with where certain things are installed, and re-install some part of packages. i discovered Pacifist which has been brilliant in opening an install package on a disk and letting me install one part of it, and if i wish, tell it where to go.
both very useful.
