In the “Currently Reading” books, I would LOVE to see some reflection of my book progress based on my updates. This was something extremely motivating about Goodreads although their UI is garbage beyond that.
This progress ban can be made much smaller than the Goodreads one; maybe even just a simple line at the bottom of the book cover that fills up in the primary color to indicate how far along you are, or a progress circle that fills up as you get further along.

I’m a UI/UX designer/developer. Would be happy to help out wherever to help get this feature live asap. It’s the only thing keeping me stuck in Goodreads. I absolutely love Hardcover’s overall look and feel and the social feature are well thought out!🏆
