*that* i can understand. i hate that Lightroom merrily saves and saves every catalog backup, without the user realizing that each one can be 1GB or more, thus quickly eating up a lot of HD space.
but at least Lr allows the user to restore an old catalog. AFAIK, ColorMunki does not allow its users to do the same, so i don't see the value of tagging the prole with the date
