There is a couple of things I would like to be included in LDD 4.0
1.) The ability to add Lego bricks on top of Mini Figure Legs to make hands for a robot like Titan Xp or other robots including my Lego Optimus Prime Model
2.) When using Lego Universe, have the option to purchase the bricks from Bricklink Website
3.) Able to make proper instructions with step by step plans like in MLCad
