Practical Applications
Presentation Aid: Duplicate a PowerPoint presentation running in a WebView to another region of the canvas as a reference for the presenter
Tiling Videos: Play the same video in sync across different regions
Educational Environments: Ensures that all students have a clear view of the content, beneficial in large classrooms where visibility might be obstructed.
