This has now fixed one of the main pain points for me and my new mac.  There’s not much that I have issues with but this was one that really bothered me.  I just wish it was the default setting.  I’d love an application that would list all of the “newb” settings all in one place so that I could more easily change them, or know that they exist for that matter.

Some other things that I have found:
