When applying filters to a flow board, the active filters are visible in the search bar. Since we are hiding content, we may want to clearly communicate that there is content in the board that is not being shown because of the filters.

To achieve that we can use an item at the end that visually represents the remaining topics:

• A label indicating "X more topics not shown because of the filters" (or "No topics shown because of the filters" if the filters hided all content) will act as a link to open the advanced filter panel (T99875).
• An option to clear all filters will allow to go back to the full board.
