Another thing I found recently about VanasKOS which may help others:

If you click to bring up the main window; in the drop down there is an option to see players in order last seen; this is really handy to find attackers who maybe have killed 1 of your guys while you were afk (I have vanaskos only on my main so he isn't always "attacked") - it also helps in the case where the attacker list is a bit long as that one isn't sorted by recency - also when you right click to add to kos from that list it automatically puts the timestamp in the comment
