Sorry if this is not the place to suggest. But I am proposing the feature to be able to look in ones chest but not take anything.

Often when I play on servers with chest protection its quite boring to go in to others houses mostly because you can never see what they got, but if you could be able to see what they have but not pick it out from the chest that would be awesome.

I second this! I came here to write a similar ticket. There should be more specific nodes for snooping.

deadbolt.admin.snoop = peek in containers and, open doors.
deadbolt.admin.bypass = actually steal or take from locked containers.
