Gleipnir is a free Chrome extension designed to enhance the efficiency of Kanban boards by enabling users to set combined Work In Progress (WIP) limits across multiple columns. This functionality helps to streamline workflow management and reduce chaos in task organization. By defining groups through a specific naming convention, users can easily categorize tasks and monitor progress more effectively.

To implement this feature, users simply need to name their columns using the format GROUP_NAME::COLUMN_NAME. For example, columns labeled as IN PROGRESS::Code Review and IN PROGRESS::Ready for Test will be grouped under the IN PROGRESS category. This structured approach facilitates better visibility and control over project tasks, making Gleipnir a valuable tool for teams utilizing Kanban methodologies.
