It doesn't "forget" page layout. It respects its geometry, but it doesn't clear the margins, unless explicitly told to do so.
Am I correct to assume that the Color/Grayscale choice doesn't do any image processing to the image (such as despeckling, etc) if the equalize illumination option isn't chosen?
It only does geometric transformations in this case.
In other words, do I get an non-degraded image as output if I choose no despeckling? If so, would it make sense not to change the DPI of the results by default? If not, what processing is being done in the output stage.
You will get a geometrically transformed image anyway. Making output DPI match the original would theoretically give you benefits only if no deskew was applied. In practice, you won't get any benefit even in this case, because ST doesn't even try to match input and output coordinates 1 to 1, knowing in most cases it's not possible anyway. Having said that, you don't need as high output DPI for grayscale images as you would for B/W ones.
The second thing I have noticed is the scrollbar in the preview/thumbnail pane doesn't allow scrolling to all images because the previews seemingly want to keep running up off the top of the page, makes work more difficult than it used to be.
I don't understand you here. Please be more specific.
I find I repeatedly have to hit page up to get back to the page I want to work on as I go through the stages. It would help if each stage reset back to the first image instead of starting on the last. I see that some of the changes were intended, but with no scrollbar *or* way to scroll with the mouse it makes it harder.
Making batch processing stop at the last page, or jump back to the top, or jump there when you launch it the next time - all of these options have pros and cons. Before the next release I'll probably make up my mind on which one to adopt.
I also see that the changes to the Page Split stage were intended, and the new code is much more accurate in picking the correct side, but I found the green arrows useful to switch if needed.
There are no more "sides" when dealing with single page scans / shots. We now have two cutters and the page area is what between them. No sides means no need to switch sides.
Scan Tailor experimental doesn't output 96 DPI images. It's just what your software shows when DPI information is missing. Usually what you get is input DPI times the resolution enhancement factor.
