The biggest gain from the massive rewrite was the ability to tie several smaller worlds together into a larger one. Previously, if someone built, say, a quaint little shed, and wanted to place it in several places around the world they would have to copy and paste it to each location. When the time came to revise the hut (and those times come many, many times throughout a project) they would have to visit each location and update each hut separately (blech). Aren't computers supposed to automate repetitive tasks?

editWorld brings the Reference system to the table. With References, that hut is built once, and then a reference to it is placed throughout the main world. It looks just like the hut, but you can only move and rotate it about to place it. Want to revise it? Click on it to open it, make your changes, then switch back to the main world where your changes are automatically reloaded and shown to you.
