A Better Goodreads Bookshelf

Hi everyone, wanted to run an idea past everyone to see if this is something that could potentially bring in some revenue. As a Goodreads user, I'm often disappointed by the quality of its UI/UX wrt one's bookshelf. It seldom inspires the same awe that a physical bookshelf does.

My idea would be to use the Goodreads API to design a much cleaner and navigable personal bookshelf (sort by categories, see those in common with others, etc) -- with a free tier as well as a one-time "paid" tier to secure a custom username within the URL link (e.g. greatreads.com/paiduser). Thoughts?
