Bluebuild adds useful blueprints to the early game. Immediately from the start you can place a blueprint and items will be placed at 5 per second so long as you have the materials. Demolishing works the same way. Plan your grand scheme from the start with Bluebuild!
If you have trouble with performance, especially in multiplayer, try turning auto-build and auto-demo off (shift+b and shift+n by default) when not in use and encourage other players to do the same.
