If I have a 200 pg. book and in the merged preview I need to find out what page is causing a problem, I have to open in Acrobat and search through. When I find it, I have to exclude the page by hand, save, open in Briss, etc. you get the idea. And I don't always guess correctly. It would be very helpful to figure out a way to make this process easier. One way would be to have a 'show single page' checkbox with forward/back arrows next to the merged preview, and a box showing which page is being previewed. When you come to a page that doesn't align, allow the user to mark it or allow the user to re-position the box on that one page only right then and there.
Thanks for considering these changes! You have saved me many dozens of hours of painful copy-paste work in Acrobat!
PDF Scissors can do this:
"It is impressive - first it scans all pages and overlays them graphically on top of each other - that way you can easily find optimal cropping size. You can preview your cropping by going through each page and adjust.
It's a java App, probably runs on all platforms. Brilliant for quick croppings!"
