 - `--foreground` is to use foreground colors instead of background
 - `--directory` is to set where the Zeek logs are
+- `--filter-conn` is to filter all the conn.log lines which UID is in other Zeek file. Therefore, if a flow produced other log appart from the conn.log, then the conn.log one is ignored. This is good if you want to know which conn.log lines do not have a recognizable protocol and are interesting to see.
