Abstract: The technology provides a computing device having a communication module configured to communicate with one or more remote services to receive content, a display module configured to display the content to a user, a user input device that includes one or more customizable features corresponding to the content received from a given one of the remote services, and a processing module. The processing module is configured to associate a given one of the one or more customizable features with a specific element of the user input device, identify selection of the given one of the one or more customizable features, and, in response to the identified selection of the given one of the one or more customizable features, prioritize interaction with the content over one or more other functions performed by the computing device.

Abstract: The technology provides a computing device and method of operation that includes receiving, by the computing device, content from a remote service. The method identifies a latency issue associated with the content, and determines a set of diagnostic options based on information about the content and the latency issue. The set of diagnostic options identifies at least one of network information or display information. The method includes generating, for presentation on a display device via a graphical user interface, a notification indicating the latency issue and the set of diagnostic options. The notification includes an option to access the set of diagnostic options in order to address the latency issue.

Abstract: Aspects of the subject technology relate to systems and methods for instant insert of external content into a content-editor application. An assistant application is provided, separate from the content-editor application, that can identify, obtain, and insert the external content into the content-editor application. The assistant application can identify the external content responsive to a user request while the user is inputting or editing content in the content-editor application and/or the assistant can provide predictive options for insertion of content based on the already input content by the user. As one example, the assistant can insert a photo related to text the user has recently typed into the content-editor application. The assistant may obtain the photo from a public source such a public web server or from a local database for the user.
