Abstract: Disclosed herein are systems, methods, and software to enhance user experiences with online services and hosted content. In at least one implementation, an initial user interaction with a user interface to a local model of content is detected. The local model of the content comprises an initial portion of the content downloaded to the local model. A subsequent user interaction with the user interface to the local model of the content is predicted based at least in part on the initial user interaction. A subsequent portion of the content is then identified for downloading to the local model of the content in anticipation of the subsequent user interaction occurring. The subsequent portion is identified based at least in part on the subsequent user interaction.

Abstract: Users are enabled to navigate a spreadsheet document presented by a web service in a similar fashion to a locally executed spreadsheet application by retrieving blocks of grid data asynchronously in order to display or refresh the area(s) of the spreadsheet currently being viewed by the user as the user navigates the spreadsheet grid or dynamic updates occur. The blocks are laid out in the browser's user interface to fill the user's viewport as well as a predefined buffer around the edge of the viewport. As such, when the user scrolls or updates occur, data associated with blocks are added, updated, or removed in the browser as required to fill the user's viewport.
