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

Please provide any additional information below:

I was thinking some way to see if the ground is protected or not, using a tool.

I was thinking when the stone is placed the corners of the outline are marked with glasspane, and can be destroyed by the player. and when the stone is picked back up the glasspanes would dissapear,given they havent been removed already.

i made a plugin request, requesting a plugin of this ticket.

Please read the documentation, there is already a /ps view command which temporarily places glass blocks at the corners plus at the foot height of the player who uses, please read the Commands Page.
