before my laptop died earlier i did have photoshop (new computer is on it's way) but I had a look into Mac's Remove white tool about half a yr ago or so... What exactly does it do? and when i tried to get it to go into photoshop it didn't work....

If it just removes all the white from a certain layer then that would be very handy, at the moment i rub out white with eraser thing and stuff which takes a long time as you probably know....
