Select part of image in prep for crop

[Charles Henebry]

In iPhoto and other image management databases, you can select a portion of an image to crop using the mouse. From what I can tell after 30 min of playing around with cns_image, the only way to set the parameters for cropping is by manually entering numbers for the top, left, bottom and right coordinates of the crop.

Am I right? I like what I see so far, but $65 feels a bit dear, especially if I can't use the mouse to set parameters for crops and resizes, etc.
