Works well, when Buttons! doesn't.

Three additional features would make this complete:
1. Actually go Next/Prev even when the display is sorted with the most recent at the top. (A workround that "Buttons!" uses is to just have an option "reverse direction of Next/Prev buttons.)
2. Option to change the text on the buttons. I appreciate you don't want to call them just Next/Prev in the initial Customize dialog - but allowing a subsequent change would be useful.
3. Persuade the highlight in the main message window to track the current message.
