What is "Use Last Session"\"Manually add Documents"?

[Mike Sanders]

If you need to have the same document (or multiple documents) checked for the second time with the same options\or different options,
you can check "use Last session docs" to do a new check for plagiarism from scratch.

If you check "add docs manually" - you will be prompted to select documents manually.

This setting is re-set at each DocManager start.
