Backlog Sprinter is a free Chrome extension developed by tkr that aims to enhance your sprint development on Backlog. This add-on provides several features to help you efficiently manage your product backlog and create useful milestones.

One of the key features of Backlog Sprinter is its product backlog management. It allows you to easily choose an issue type to express your "product backlog" and arrange backlog items by simply dragging and dropping them. However, it's important to note that this feature requires a "Premium" plan or higher due to its use of the "custom attribute" function to store the order of product backlog items.

Another useful feature offered by Backlog Sprinter is the ability to create new milestones for sprints. This feature automates the process of creating a milestone with a start and end date, moving uncompleted issues from the currently selected milestone to a new one, and archiving the old milestone. It's worth mentioning that this feature is available to anyone except guest users.

Overall, Backlog Sprinter is a valuable tool for streamlining your sprint development on Backlog. Its intuitive interface and practical features make it a convenient choice for managing your product backlog and creating milestones.
