Recently I've been frustrated by the fact that we have a number of tickets open on Pidgin's Trac that deal with inadequacies in the preferences window. The biggest complaint is that in a number of configurations, the preferences window is too tall to fit on a screen. This has only recently become a problem with the advent of the so-called "netbook" with their nearly microscopic screens .
