Clicking on the Unanswered button, you get 3 tabs :
My tags - this tab lists answered questions, but the answer was not accepted. The questions seams to be sorted in some strange way (by number of votes). Why are they not sorted by date? Why are questions with answers listed?
Newest - this lists all possible tags listed by date. Not very useful in my opinion. Clicking on a tag that I am interested (one of favourites), switch to Questions - newest.
Votes - again not useful. Lists all tags
No answers - lists all possible tags sorted by number of votes.
What would be useful is to list favourite tags sorted by date. Any thoughts on this?
