exactly.. they've added all the other options. Now after you peek, you pop back to a menu to allow you to attempt to open or destroy it--just need to add the option to open with a Forbidden Key and have it -1 the key from your inventory just like when you use ninjutsu it -1's a tool. Granted the coding isn't the same, and will require some extra work--but the concept is similar. This would save you from having to cancel out, hit your macro, retarget the box (and risk targetting the wrong one because you have 3 piled on top of a each other) and then popping it open.
