Bug Fixes.

While this isn't really a pull request, I just thought I'd let you know of these commits I pulled from CAF a while back. aa5126a8a9da73e694b99c3a4843d5b2380ef9eb and d7a9e9d6ef0454149eb1fb22f3f4518b0ad0b403 fix some minor preview bugs in Accessibility Settings; while not really needed, the less bugs the better, right? 

The rest are just preferences picked out by me.
