Thanks for the feedback.
The two options are for logging activity:
"Save copied URL to database" - Record from which URL content was copied.
"Save copied content to database" - Record copied content.
If they are enabled you will be able to see them in your main plugin page in a table. This is handy if you wish to see what content is being copied and your most popular pages.
"Read tag" is the custom prefix which appears before pasted link.
Iin the page exclusion you can list pages you don't wish to be included in the script: e.g. /contact-us/ (so people don't get auto attribution pasted if they should try to copy your phone number etc).
Hope this helps and we'll definitely try to include better screenshots and videos.
