I would like a configurable timer for the crate to be protected such as:

Crate Protection Timer: 300

This would protect the crate from being looted for by anyone else for 5 minutes after it unlocks. After that, anyone can loot it.

^^ I would love that too, great idea and great plugin.

Sorry for the late reply, I've been a bit busy with other things. I'll add this in the next update.
