Hi,
can you add the properties for the "protection block" about the heigh that the block protects from: its heigh coordinate, to: the sky? Because if anyone go in air where there isn't the protection can use the lava or water to grief, and if I set an hight value to custom-height the protection goes underground and it is usefull or funny for miners...
Regards.

I jet my house protection to 200 height so it covers bedrock to clouds. I think it's a good idea to let people protect underground with their house because most people like to start mines from within their house. but still a custom altitude point for height is a good idea and should be implemented.like split custom height into 2 options custom-height-up and custom-height-down.

You can set the custome height to something like 512 to cover ceiling to sky no matter what altitude the block is placed at.
