[Someone]

1) Mailbox-Mode-Toggle
A mode for containers that allows people to view and deposit items, but only the owner can take them out. A nice way for employees to deposit resources and to have an IC mailbox without OOC nerds stealing it.

2) Editor-Access-Toggle
Allow House Editors to access owner-locked containers. For people that own a shop and employ workers, or have an IC wife/husband/family, so that they can have access to items without running the risk of some jerk-off coming along and stealing everything if they forget to lock the door.

Or simply wanting to have something stored in a public area for convenience.

3) Upgrade furniture (?)

Upgrade or customise your containers to store more items inside.
