I've been a MacBook Pro user for just under a year now and am a bit frustrated with the photo viewing/editing software. I don't mind the basic editing features on iPhoto but I hate that I have to export each photo in order to have it save the changes I have made. I also hate preview. One photo at a time is incredibly annoying. Can anyone suggest a program that will let me easily view photos and also have the option to edit and save? Much appreciated.
