[Request] Bigger icons.

I have a big screen at work, and it's very difficult for me to go through the apps menu with their tiny 16x16 size, i physically have to move my head closer to the screen.
It would be great to offer bigger icons as an option (32x32 or even 48x48). I think it will be usefull for those who are using large displays (and large resolution), and those who have vision proplems.
