I like the new layout better.
But, don't forget about the TAB Index. Many developers actually don't care about this, but when you deal with tons of settings and you just want to slightly adjust many of them on the keyboard, hitting the TAB key to jump from one to another is much faster and more convenient than selecting everything with a mouse.
The TAB Order should be layed out as follows:
within a group of controls: from LEFT to RIGHT from TOP to BOTTOM, making sure that you're going in this order only among controls for a single group, in other words, among controls that logically and functionally belong together.
