It's a similar approach to the same problem. Code Bubbles make the jumping more palatable. I'm not sure you would need such a drastic change to the traditional IDE look to implement what I describe. You could (for instance) simply have the code (set off stylistically) expand in-line pushing the code below it down the screen. This would get rid of the jumping altogether.
Of course this approach raises its own issues. Can you expand a function within an expansion, how would that look, usability, and so on.
