Who really cares if people know what's in your inventory?
Unless you carry around a bunch of tools renamed to non-child appropriate things
~ @Enron
although it would take a few seconds to implement, there's simply no use or need for it. Having such perk is just going to cause more hassle than it will do good, will make people for an easy target and people may not want getting spammed for whatever they have in their invs
if someone has tools named something than that's up to them, doesn't mean everyone else needs to see it
