As for the calc() fuction, I believe the given example can be accomplished quite easily with simple css2.1. Usually a fixed-width float and a margin (same size, same direction) will do the trick.
One thing missing from the list (and on top of my own list) is more control over css background images. I would love to make better use of css sprites but until I can somehow dynamically crop a specific part of the image and only show that part css sprites are only useful in borderline cases. I try to make my css as flexible as possible, so hiding other parts of the sprite based on px values is not something I generally do.
