I've made a reading challenge for myself to read most of my physical TBR in 2026. I added almost all the books I have to this challenge and I thought it could be really fun to have a button on the challenge page for the app to pick a random book from the books I/someone else added! I just finished a book and then I could press the button and let the app pick my next read for me :) I have no clue if it's easily achievable, so no worries if it's not!
