The options under the
Questions tab are a mix of sort options and filter options.
Active sort the questions by those attributes and display ALL questions (thus making the label to the left
All Questions accurate).
Unanswered, however, are filters and only show questions with bounties, questions with lots of answers/views (unclear) and questions with no accepted answers respectively. In other words, those three show a subset of the questions, thus making the label
All Questions inaccurate and confusing because it implies that these views are sorted views like the other three rather than filtered views.
It would be better if they were a) separated into sort and filter options, b) labeled to correctly reflect their respective behavior (i.e. "All" changes to "Featured/Frequent/Unanswered") or c) ?? I'm not sure the best answer, but the current design is misleading.
