There is any option in the user profile that allows indicate to the system that, when a question is opened (click on question link), it must present the answers ordered only by votes (regardless of the accepted answer) ?
It's pointless to have this in the profile, since each site "remembers" the last sort you've used, for good, using server side storage attached to your account. (Not a cookie, i.e. cross platform.)
This means that once you sort answers by "votes" it will always sort by votes, unless you choose to sort by something else.
The fact accepted answer is on top regardless of its score (unless posted by question author) is by design, and can't be changed.
If you want it changed, you can start a new feature-request question here.
