Technologies are disclosed that enable a computing system to collect and process user preferences regarding content that is shared in a collaborative workspace. By the use of an input gesture, individual users of a multi-user sharing session can provide a vote for a portion of content indicating that they favor (“up-vote”) or disfavor (“down-vote”) the content. The system can collect and analyze the votes from each user. The system can then modify the content based on the votes. Modifications to the content can include, but are not limited to, rearranging selected portions of the content, generating annotations, generating one or more UI elements that bring focus to portions of the content, identifying high-priority content or low-priority content, or deleting portions of the content.
