Yes, Book Like a Boss has a roadmap. We decided to include this after we saw the value in sharing with our awesome Bosses our goals, work in progress and immenent feature updates. We also like to offer a space for Bosses to submit feature requests.
This link: https://roadmap.booklikeaboss.com/ will take you to BLAB's roadmap.
You can submit feature requests and upvote other Bosses requests.
