The separators - I took one out, actually, there used to be another. In general I like fewer of those, but I kind of like the one and only one here. ^_^

I also put in a lot of work on text entry boxes to make them less distracting when not looking at them - not just getting rid of the 3D like we both did, but also bringing their height more into range of the larger text. And my minimalist buttons, of course - they serve the same purpose.
