A good addition to the settings of a single filter is a search by its values. When there are a lot of these values, it is good practice to display the search field by the name of the filter, through which you can quickly find what you need.
It would also be nice to add a filter window height parameter to the filter settings. When the filter has many values, it is better to limit their display by height in the window, also adding scrolling to it.
When displaying values through checkboxes, it would also be nice to be able to display values not only under each other from top to bottom, but one after the other from left to right. The second option in some cases will help to show the values more compactly.
