I’ve been using Storygraph for a couple of years now and love it. The only feature it’s missing for me that Goodreads has (although its implementation is awkward anyway) is the ability to add a note to a book you haven’t started yet.

My workaround for now is a tagging system with friends names like #recommendation #recommendation-amy and if I want some more detailed info, I made a custom shortcut to transform a Storygraph share URL into a note in my book notes folder in Obsidian.
