I'm evaluating PM. I'd like to say it's a great implementation for a front end work flow. It's a very difficult task to know where to draw the line on feature creep.
Rotate Crop: For situations that require very little post processing PM is sufficient in many cases to be all that's needed for the majority of the images. I find the crop function very useful. The ability to rotate the crop would eliminate the need for further post processing in many cases.
IPTC Keywords: It's not an organizer, but if the keywording capability is present, then searching across directory organization would be extremely helpful. I'd like to be able to apply the keyword search to a directory (sub)root or a group of open Contact Sheets
Thanks,
Roger
