To have some kind of filter bookmarks so to "save" recurring searches or slicers slections (and avoiding repeating over and over select/unselect to surf in the data).
After a user has applied any combination of slicers, filters and data selections to a Power View sheet, they should be able to bookmark or save the state of the sheet so that they can at any time in the future revert to that state as well as share that bookmark/state/view with other users. This is a key feature to allow for persisting and navigating view of interest, as well as collaboration, especially in the web-based Power View rendering. Competitor products such as TIBCO Spotfire have been doing this very well for years and it has been mentioned as a weakness of ours by many of my customers.
