I love storygraph but I feel like its impacted my reading habits in that I feel like I HAVE to finish a book cover to cover. I'd love to have an option for partially read (as opposed to DNF) where it's a book that I've read excerpts from, say in a class where we read a chapter of it, and while I want to read the whole thing I want to recognize that I've read part of it (but did not abandon it like a DNF). I have added my own tag of this but I think it would be a cool feature.
