In the new navigation UI, every entry in a questions list seems to be either 'asked' or 'modified'. This seemed odd to me so I opened a new SO session in a private window that wasn't going to read my new navigation UI cookie option and sure enough, there are 'asked', modified' and 'answered' categories at the least (may be more that I am unfamiliar with).
Edit: My original narrative may have been unclear. This is what I am referring to in the old UI.
If I respond to a question, I have posted a potential answer (such as it may be). I have not 'modified' the question. In the new Nav UI, the 'Answered' designation appears to have been supplanted by 'Modified' in every case even when no edit to the question exists.
