A "Stop Publishing" feature in Firebase Studio is a crucial missing piece. Developers often need to halt a deployment due to last-minute bug fixes, accidental pushes of unfinished code, or new features becoming ready mid-deployment.

Currently, once a publishing begins, developers are forced to wait, then initiate another deployment to correct issues. This wastes time and risks exposing users to broken versions. Adding a "Stop Publishing" button would provide immediate control, allowing developers to swiftly abort, fix, and redeploy, significantly improving workflow efficiency and reducing potential downtime. It’s a small addition with a big impact on developer agility.
