When I'm viewing a query log, there is a controllable limit of total queries to be displayed, of which blocked queries make up a varying fraction of. As I wondered in my matching feature request, would it still be a performance risk if those block lists were only evaluated when the queries were displayed (and just for the queries displayed)? If it were noticeable, perhaps a checkbox to let the viewer decide whether or not to display the blocklist (off by default).
Just thinking aloud here. Thanks!
