(For Realm and Server Owners): Searching inventory of players & containers

I am a realm owner who tends to keep a realm world for awhile. I had several incidents where I needed to ban a player from my realms because of stealing and snooping through peoples stuff. A crucial problem I encountered is their is no easy way for a server or realm owner to search a players stuff or containers they may have hidden stuff in. That is built into the actual game that does not require commands or knowledge about how to use them (Which some owners my not understand or may need to look up alot of stuff about them.).

I could not get any items the person stole that where in their own inventory, whether they where in the game or not. I even enabled cheats, disabling Everyones Ability to get Achievements in order to try banning the person by commands as my search result on how to ban a hacker (A person who stole a players account), in order to ban them from the server side not just through realms, which i couldnt.

■ There needs to be a game menu for server/realm owners and moderators to search players and the chests they use. Note:

●A notice for the entire server should be shown when this is done, so those activities cannot be hidden by a host or mod given permission to do so for easy abuse of power.

●These searchs should work on any user whether they are on the world or not, or have been banned or left.

●If they possess an item that was taken from a container, and the item was renamed by another person, than this data can be seen by the person conducting the search.
