I've just discovered this plugin, it looks very interesting and I'm going to give it a try. I just wanted to point out that some of the info is confusing because you're using the word "lend(ing)" when it should say borrow. The main account would be the lender, and the one playing from the main account using family share is the borrower. So, for example:
"Auto Kick: Family share accounts": false, // Auto kick players that are lending (Family sharing) the game.... should be:
"Auto Kick: Family share accounts": false, // Auto kick players that are borrowing (Family sharing) the game.
