Even is the feature is not officially supported, Snow Leopard is now able to mount NTFS volumes with both  write and read support.

NTFS Mounter simply uses this ability, and provides a simple user interface to the mount command for NTFS volumes.

User interface is very similar to AirPort : simply click on the icon to display a menu with NTFS volumes name and select the volume you want to write on.

· Automatic volume unmount volumes are now automatically unmounted before trying to remount it with write support, if volume is not busy.
· You do not have to manually unmount/eject it anymore.
