Few things that got on my nerves is that in 3.0 you can't even set your fonts without hacking some files or digging up settings from dconf-editor (-1). The default antialiasing setting sucks (-2). 11pt default font and 96px icons in gnome-shell, are you kidding me? Do gnome-shell devs think that I have 1920x1200 15" monitor? (-3). As it was in the case of gconf, with dconf, even more settings are hidden from the user (-4).
