The Filter Panel widget is now renamed to Filter widget.
In addition, the widget offers a new configuration option in its General Settings. In particular, the new Display mode drop-down allows you to choose whether the filter should always stay on top of the dashboard, regardless of your scrolling, or should be displayed as a regular widget.
As the name suggests, the Sticky option will make the widget stick to the top of the dashboard. When that is the case, the widget’s title will be hidden, along with the widget’s Lasts updated property next to the title.
The Draggable option on the other hand allows the widget to behave like any other widget.
