This plugin allows you to pick any block and "block" it. It uses the permission system so if you want like the builders to have access. Just give them the permission! We also implemented a way for your players to know what blocks they don't have access to. (/rblocks)
I have been looking around and I have not found a plugin like ours.
There are many for items but ours is solely based for blocks.
And I guess you could get those plugins and whitelisted blocks that way BUT...
Our plugin is small and really easy to navigate through.
You don't have to spend for then 5 minutes in the config, like other where you spend 30 minutes.
Our Config.YML is really small and no much too it.
The permission system is really easy to use and make. (Go to the permission section to learn how to use permissions)
