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).
I think for advanced users that Power BI is poised to be able to win over, this is a real head-scratcher. In large and/or complex data sets, there can often be more than one view of interest when investigating operational metrics. For example, I could be using PowerView to explore many months worth of a servers performance monitor data to determine the cause of a performance issue. What I have found is that there is often a progression of views that I work through to triage such an issue. Also, when immersed in data exploration, there can be a significant amount of rework to reverse course, as one often does. Needless to say, it is error prone and time-consuming to repeatedly work through these progressions and lose them every time. Regrettably, this isssue also exists for Pivot Tables and Pivot Charts. The point I'm trying to make is to potential voters, is that in certain complex use cases, the inability to save and quickly navigate to other saved views involving filters, slicers, timelines and layout is shifting the focus of advanced self-service BI users from the business issues they are trying to solve, to trying to find a suitable work-around to this notable gap in functionality.
