In a previous version of Codecov, there were indicator numbers within the Codecov UI when looking at files. They were placed right next to the line numbers, and their purpose was to show how many tests were covering that specific line. I do not know if that number also provided more data (such as the specific test covered that line), but we've had numerous prospective clients who are trialing ask about this and if it is possible. In addition to the prospective clients asking about the feature, we also have currently clients that used and appreciated the feature in the old version of Codecov and are unhappy that it is not available anymore.
