And on top of that, A lot of what you see there doesn't work, buttons don't do anything, so to make the UI functional will require a lot more code.
Still, it's a nice looking interface and if you want exactly that look, the .js files can be copy/pasted. It is a lot of work to do a draggable interface like that.
If only he'd have used shorter variable names! While he did massage the layout to get to 100 lines, I don't think it's that bad - the stuff that is on one line belongs there, even if usually it would be split over several lines for screen width reasons.
If there is no limitation on line length, I can replicate it in one line of code.
