As of right now there's very limited options when it comes to guild permissions. We should be able to add individual permissions for gates, containers, and structures. We can give different permissions to different ranks in the guild, but there's not really a point to it. I can restrict access for a member to interact with chests, but with that they can't even open a gate to let themselves in or gather fiber on the claim. I can give a recruit access to open a gate, but with that they also have the power to take anything want. In real life, a guild leader could lock a chest so nobody has access to it except the guild leader. Why can't a feature like this be implemented on an individual structure.
