Skinnable Applications
I'm starting to get a little bit cranky at skinnable applications. With Adium as the exception (skins can make it so much more low-profile, the way an IM program should be), all skins do is make the program stand out like a sore thumb on my desktop. Firefox, I learned to deal with. But Songbird's "Gonzo" theme is a piece of shit. Thank god someone made a skin that I could download to force it to use the same look at the rest of Gnome does.
