Several methods are described herein to allow users to manage and synchronize views in a multi-user application with canvas (infinite or otherwise) and limited or unlimited zoom. Without these synchronization methods, coordinating views is very difficult, and may lead to chaos as one or more of the users gets lost on the canvas. A 'View Sync' method provides for many-to-one synchronization, where many users are automatically synchronized with one user. A 'Sync View' method provides for one-to-one synchronization, where one user is synchronized to another user's view. Preferably, off-screen &#x201c;activity indicators&#x201d; also are used within the viewport to provide visual cues regarding where other users are drawing or creating content on the canvas. Tapping on an activity indicator preferably performs one-time Sync View with the selected other user.
