I don't want to talk for Chris Granger, but my intuition tells me that the features you listed are things he considers to be the baseline for a modern editor and are not the true reason he's building Light Table. I think his goals are more about making a real product with the capabilities of the demo IDE Bret Victor showed in his Inventing on Principle talk https://vimeo.com/36579366 Eclipse is nowhere near this today, and perhaps it never will be. I'm backing Light Table because I think Chris has a shot of getting there.
