There really isn't anything to change with NUI. The author does have a few extra skins and information panel to integrate recount, omen, the zone map etc.

I am so happy using NUI. I don't have to worry about addon updates fucking everything up. Just drag your spells, items to the bars. I use bindpad for unlimited macros/binding so I don't care if the bars can make macros. But the NUI bars do have the ability to bind directly to them.

I don't need to toss in a screen shot because my screen looks just the authors screenies, just toss in the jamba window on the side.
