I'm looking forward to trying out the Actions automation tool. When I'm doing webwork, I need to resize lots of images into thumbnails. That should come in handy.
The Web Photo Gallery tool is terrific! However, I still have to learn how to "tweak" it to get the look I want.
The Contact Sheet facility will be my most used automation. It allows me to keep a 'chronological diary' of my photos as I take them.
The ability to gang scan is a dream come true!!
And the ability to automate the numbering system is intriguing. I'm still debating whether I want to override my camera's numbering system, but I like the idea of dating all photos with this tool.
