Comment 82 for bug 386150

Here is a comparison between the size of the chrome (gray) and the area where you see the actual files (green) in the default nautilus window size on a new (guest) account. This does not take into account tabs or the bar that appears when you're about copy files to a writable cd.
Solving this bug would mean more space for the green area.

With my icon designer hat on, icons such as Visualization in Rhythmbox benefit from a label, as it's a much less common symbol in our everyday lives than arrows (that are practically everywhere), so I don't believe dropping the labels from those icons will impact notably on the learnability of the interface.
