The Filter Bar is useful given the ability to pin on multiple canvases in the same workbook. That said, it would be much improved if there were an option to see all of the dimensionality and filtering thereof that is taking place in the Filter Bar. At present a user has to scroll left and right and it's easy to lose track of what filtering has been done. A pop-up or other top-to-bottom viewing option would be a significant improvement over the current left-to-right setting.
