Fixed Selections Panel
It would be handy to have a panel where we can put slices into. Could be done already now, but, when maximizing a visual it should not overlap that panel.
In this kind of behaviour we could place several smaller visuals on a tab, users selects (maximizes) the wanted visual but is still capable of change selections.
I would use this functionality because at this moment we cant have linked slicers on multiple tab pages ...
