I'd like a plugin were you could select an area, then command the plugin to "every day, restore this area to the way it is right now." So players could edit it, but then once a certain peroid of time rolls around, it's restored. I'd use this to allow people to collect sand from beaches, but then the beaches are restored periodically so there isn't a huge ugly crater by the water, and when they want sand again later they don't have to go trekking to far-off places for it.
