Abstract: Computer-implemented systems and methods for controlling presentation in a web application among remote users over a data network. A web application has a remote control user-interface (UI) element that allows one to turn on or off remote control presentation. Presentation data is shared in the web application among remote users depending on whether the remote control UI element is turned on or off. A system includes an inter-browser controller coupled to the web application. The web application outputs a page having a remote control UI element. The inter-browser controller controls sharing of presentation data selected by a first user through the web application to other remote users depending on whether the remote control UI element is turned on or off.

Abstract: Computer-implemented systems and methods for electronically propagating content to downstream users. A content management system is configured to manage storage of a collection of content blocks. Each collection includes multiple layers of content blocks including at least one authoring layer customizable by one or more authors. A content authoring tool enables authors to perform one or more modifications to add, hide, remove or edit content blocks and automatically propagates the author modifications downstream to lower levels accessed by users of the content management system.
