I'll continue improving on the interface elements bit by bit. In v2 you'll get success rates for task assignments and any new secrets you discover will be logged in the daily reports. Open lock icons might confuse people, but I could add an asterisk or something to make them more visually distinct.
Orc Jail is the third highest voted in the poll at the moment, so it's likely to be added around v3 or v4, but I don't really plan to make it mean-spirited.
