Can I filter to see what a certain player has seen me showdown whilst he was at my table ?

You could do this in a custom report for yourself - if you create a report using the following filter expression:

holdem_hand_player_statistics.id_hand in (SELECT hhps.id_hand from holdem_hand_player_statistics hhps player p where hhps.id_player = p.id_player and p.player_name = 'Villain Screen Name')

making sure to leave the single quotes and use the villain's actual screen name you'll see your stats filtered to hands he was dealt in.
