I love Mint and how fast it is changing. So much so that it is now distro 1a for me right behind PCLinuxOS (and may soon overtake it). However one thing that Mint does not do and PCLinuxOS does, is allow me to use the navigation buttons on my MX518 right out of the box. This is a feature that is very useful to me and to anyone else who has these types of Logitech mice, so I think this feature would really be appreciated by a large number of people. Hope you can add this small feature in the future.
