[Usability] Selection buttons

[Maurizio Colucci <seguso forever tin it>]

Hello,
Using control and shift to create complex selections is undiscoverable, 
and difficult for common people. OTOH, in icon view it is often 
difficult to select a precise set of contiguous files without using 
those buttons. For example, in order to drag some mp3 files to a playlist.

What about adding some GIMP-like toolbar buttons representing the 
selection mode? These would be mutually exclusive: "add to selection", 
"replace selection", "subtract from selection".

Just a thought.
