Patent attributes
In some examples, additional content is provided with the main content of a content item presented on an electronic device. For instance, an occurrence of an event may call for presentation of an additional content portion concurrently with the main content of the content item. The additional content portion may interact with other additional content portions, the main content portion, and/or user inputs. In some cases, the additional content portion can be implemented by one or more plug-in modules having designated roles for providing respective different types of additional content. Accordingly, some examples provide a cross-platform module that receives events, selects one or more plug-ins in response to a received event, and causes the one or more plug-ins to perform a desired action for rendering and compositing additional content portions or features to be presented with the main content of a content item.
