Classroom Tab Preserver

Keep your active tab (Classwork, Grades, People) when switching between courses in Google Classroom, bypassing the default Stream page. - Persistent Navigation: Move from 'Grades' in Class A directly to 'Grades' in Class B. - Maintains Sorting: Keeps active URL parameters (e.g., sort by last name). - Smart Filtering: Ignores class-specific IDs (like grading periods) to avoid broken links. - SPA Support: Works instantly without page reloads.
