@Pierre: The option sounds very useful but at least for me, the implementation in v0.99.7 is clearly less useful than previous default behavior, so I now activated "Load 'Default values'". Example: I am scanning letters. For 1st image, I crop to content, press SHIFT+S, set resample=true + mode=size(pixels) + width=1024 (height becomes automatically set to 1525) + keepRatio=true, OK, save, close file. In next image, I crop to content, press SHIFT+S, width is set to 282x208 – by far too small (text is absolutely unreadable) and neither any of the values is what I did use last time, nor the width/heigth relation. I would expect width=1024 is used all the time, because this is was what I did manually enter, and heigth is computed accordingly due to keepRatio=true. Similar issues happen with digi cam photos, screenshots etc.
I did try to understand better by reading documentation, but
https://www.xnview.com/wiki/index.php?title=Resize (for classic XnView) was the only search result for search term "resize".
