I would love it if there was a feature that compiled data from my 'To-Read' and 'Owned' lists to filter for a list of books I want to read and don't yet own.

This would hopefully be called 'Gift Suggestions' and it could be something with affiliate links that I could give to friends and family members when they're looking for birthday and Christmas gifts for me.

Preferably, it would filter out different editions of the same book, too! So it doesn't list a book as a gift suggestion simply because the one I own is a different edition to the one I said I wanted to read.
