Like I have mentioned elsewhere in U59, SSG introduced a floating Locked chest symbol, but for some strange reason didn't do something similar for generic: Locked doors or Locked Levers.
There are some doors that do "auto" open when you pick their lock. In fact most 'breakable doors' can be unlocked with 'Open Lock'. There are several generic Levers that you can also unloosen with 'Open Lock', just off the top of my head; Spies in the House, Bargain of Blood, Search and Rescue, The Haunted Halls of Eveningstar and The Underlane Assignment... There'll be more, but I cannot recall, which at the moment.
Dragavon, I'm not in particularly in favour of changing to the current behaviour with regards to: Open Lock and Locked doors or Levers. Locked chests are less of an issue in most cases as the open and closing of the lid is just mostly cosmetic and reveals the chest contents unless they are actually Mimics.
Also there are tonnes of breakable doors that can also optionally be unlocked – a lot more than most people realise... On the whole most people will break the doors down if they have the ability to smash them to splinters, etc.
The Forgotten Caverns: Locked "breakable door" example.
I still wish to have an actual choice of how I interact with such doors and in the majority of cases; I will actually want to SMASH the door down and NOT waste resources and time attempting to pick the Lock! So I certainly oppose such changes with regards to; Locked breakable doors.
When I'm on my Assassin there are some of those dual-propose "locked breakable doors" I wish to break and others I chose to unlock for obvious reasons. I'd say the majority of them I would choose to break by swinging my weapons (depending upon mobs and dungeon layout) in either case I still want that choice and not for the default to be carelessly overridden by auto: Open Lock! :-/
