The trouble with that is the level of control is fairly crude.

I hit this recently in the context of cropping out a section of an 
image. I needed a 1024x1024 for an external FFT application. Doing that 
with the mouse is not very realistic.

I would have liked to use the arrow keys to fine tune the selection but 
as soon as I let go of the mouse drag operation the dimensions of the 
selection are not longer displayed.

This seems like an oversight since until the selection dimensions are 
confirmed the co-ords need to stay up.

I ended up cutting out larger and then using ImageMagick to finish the job.
