It would be helpful to me in screening large numbers of images if the Batch Progress window, in addition to containing the Terminate Batch Process button also contained a second button that moved the batch process to the preceding input file so that I could backtrack. I suppose this might also be possible using the File Open transform window if it could be kept open. Also, for what I am doing, it would be a little nicer if the default position of the Batch Process window did not overlap the output image window.

Just to be clear, I am assuming you are running a batch job and have set a breakpoint somewhere in the branch that is being executed. When you hit the breakpoint, you want to have the ability to select a different image from the file list and restart the batch job from there. Is this what you mean?

Yes, I am running a batch job and I have a breakpoint in the branch. I would like it if, when execution has stopped at the breakpoint I could resume the batch job from the file before the file whose execution has just stopped at the breakpoint. Being able restart at any position as you wrote, would be fine if it requires no more than clicking on a button in a window that is already open.
My need arose when I was screening 1000 shots of the sky as I tried to capture one of the Geminid meteors from the recent shower. Because I live near a city and the sky is not very dark, to see the meteors I need to enhance their visibility by taking an image, blurring it, subtracting it from the unblurred version, then increasing the brightness (same steps as unsharp mask, but greatly exaggerated). To verify that a candidate track was not the faint trail of an airplane or satellite, I needed to closely examine one or two images immediately before and after the image containing the candidate track.
