Smart Log/Lost Building Finder/Coordinates Snapshots

sometimes, players may get lost in the map and don't find a building they where working on, if you think they should be careful and take note of the coordinates you're right, but i still want to suggest a "Smart Log/Lost Building Finder/Coordinates Snapshots", in the first case i'm talking about a log that keeps note if and where the players spend any amount of time on one or more specific points of the map building something, the Lost Building Finder would be a tool that elaborate specific input provided by the player like "search any structure that has at least or specifically a certain amount of consecutive blocks of a specific material in one or more coordinates"

Last, but not least, "Coordinates Snapshots", a command that instantly register the actual position in a list with customizable names
