Page Control adds 3 blocks that allow for basic lag management and automatic activation of redstone machines in your base. The player detector emits a redstone signal when the user who placed the block is online and will stop when the player logs out. This is really only useful for multiplayer servers and has very little use on a singleplayer world. The item void block and the serverwide item void block both delete dropped items and have the same functionality apart from the serverwide having a range of the entire server and the regular item void having a smaller box around it. The item void can be activated on right click of the block or by a redstone signal coming into it.
