What is the enhancement in mind? How should it look and feel?

There should be a command such as /ps give <player> <protection>
This would also mean that you should be able to create predefined protection blocks.
Let's say I want to create a protection called house_protection. I create the protection lock using /ps create <dimensions> and then I place it down. I then start to add flags to it such as pvp deny, etc. and then I do /ps define while looking at the block. This would store all the info about the protection block (size, name, block type, flags, display name) inside a yml file named by the name of the protection block (in our case, house_protection). Then I would do /ps give <player> house_protection to give the player that certain protection. He could also buy those from shops by putting on the second line of the sign the name of the protection.

Please provide any additional information below.

That's all!

Good idea! I will implement it.

Awesome! Any possible release date?

I don't know, I have to stabilize the plugin first by fixing it bugs.
