1) It would be nice to add an owner system on props. Only the player who freeze the prop can grab, copy, delete or unfreeze it. There will be less abuse. Of course admins can access player props.

2) A system for saving props on a map for admin only. The admin can save props and when the map is reloaded, he can if he wants to load his build.

Thanks for reading.
