Is it possible to see the percentage of answers in a user-profile that were 'accepted answers' and search or sort his list of answers for accepted answers?
If not this would be a nice to have feature. The accepted answers of a user are often the most interesting for others to read.
This could even get some badges for 100 accepted answers or 100 answers and an accepted rate of n% or more. I'm not sure, what percentage value would make sense here, would depend on the average accept rate per user.
