Secondary Screen is a free Chrome add-on developed by digisecondaryscreen. This tool is designed to make it easier to move popup windows to a secondary screen and allow them to go fullscreen. It specifically moves popup windows that have a `` tag.

With version 1.0.4, Secondary Screen has fixed an issue related to handling the "Scan again" option after the setup for the primary and secondary monitors is changed. This update ensures smooth functionality and seamless transition between monitors.

Secondary Screen is a valuable tool for developers who work with multiple screens and need to quickly move and maximize popup windows on a secondary screen. By simplifying this process, it enhances productivity and improves the overall user experience.
