We really try and avoid extra settings for minor interface elements like this. Generally when something changes there is a push back from experienced members, but over time this resistance fades and it's no longer a hot issue and they adapt their habits to suit.
Adding a setting adds extra technical debt to the product which means more inflection points for bugs, cross setting issues and so on.
If it's still a hot issue in a few weeks, please let me know and we can look at it again.
