A couple things:
1) You cannot change the size of the thumbnails (I'm going to add an option for that in one of the next updates).
2) You can click the three dots at the bottom right corner of the a thumbnail and then tap "View Page" if you want to see a full page rendering
3) The page order feature will not modify your PDF if you just remove, duplicate or rearrange pages. It only modifies the PDF if you insert other files, templates or blank pages into your PDF (or if you select the option to update the PDF with the current page order). MobileSheets will always warn you if the file will be modified, as that was added after feedback from users.
