Multi-Columns Slicer

I would love this, considering that our reports are usually in landscape mode, having a single long column takes up unnecessary space.

This would be very useful. Allow the slicers to be set to how many columns you want to display, just like Excel slicers. Layout > Number of columns.

Yes, the ability to put many rows of slicer fields in more than one column would be very useful. For example, a slicer across the top of the page with a dozen or more small text-options, instead of a slicer down the side.
