Yes!!! This is the only GoodReads feature that keeps on there! So many alternatives out, but GR quotes function is just so good.

With the addition an import feature from Kindle Highlights and other readers I do believe this would be a great feature.

These quotes could be submitted publicly for a book and merged with other users.

The quotes are to be upvoted and downvoted seperately.

I would love an export feature of my highlighted quotes as well.

One thing I like about Goodreads on desktop is their quotes feature. Pulling from a source like WikiQuote (https://en.wikiquote.org/wiki/Main_Page) might be a way to replicate such a feature for Hardcover
