In some implementations, a user may select a category, attribute or term related to content item. During presentation of the content item, an electronic device may visually distinguish (or, alternatively, hide) at least one portion of content associated with the selected category, attribute or term. In some examples, a user interface may be displayed to enable the user to select one or more categories, attributes, or terms related to the content item. The user interface may further enable the user to select a graphics scheme to be used for visually distinguishing at least one portion of content corresponding to the selection. Selection information identifying a portion of content to be visually distinguished or hidden may be sent to a content provider, such as for synchronization with other instances of the content item on other devices of a user, or for aggregation of the selection information by the content provider.
