Have you ever wondered how new features are developed at Google? We start with a problem that needs to be solved, then consider what the best solution might be, so that our products can be more helpful. And, when we can, we like to get feedback from you (and Googlers themselves) before we officially launch so we can refine and improve.

Beta Features is new from Play Books, and it lets you test out experimental features on the web. This project originated with Dan Kimberg, a software engineer who joined the Play Books team to perfect a product he’d been a longtime fan of. Self-proclaimed bookworm and lifetime lover of literature, Dan was eager to personalize his library and make it easier to browse and organize his collection of books. He knew that other readers out there probably felt the same way—so he got to work.

These features may lack a bit of polish; they might evolve, improve, disappear or transform into new Play Books product updates. They’re experimental, and Dan and the team want to hear what’s most helpful to you. We sat down with Dan to learn more about the inspiration behind Beta Features.
