Next button should take you to the next file when you reach the end of the file
This is how Beyond Compare works (great tool by the way). It prompts if you have unsaved items, don't know if that should apply here.
At the end of a file, we currently are prompted to continue from the top of the file, or do nothing. Some people will probably still want those options, so if the prompt allowed all three possibilities, that would be ok.
