Here are the drop down options under "Needs Answer":
This drop down is specific to "Needs Answer", not generic over all tabs.
Here are what I imagine they should do, if you keep all four of them:
"All" - Should display all questions that do not have an accepted/upvoted answer and featured questions.
"Needs Answer" - I'm not sure about this one. It seems to duplicate "All", not to mention duplicating the tab... it seems there's some interest in the option to exclude "No answer" questions, so maybe it shows only questions that have low-quality answers or answers that don't have upvotes.
"No Answer" - This should show only questions that have zero answers.
"Bounties" - This shows only questions with bounties.
So, here's the problem:
- "All" currently shows some larger subset of questions... even ones with accepted answers. I'm not sure what it's showing as it doesn't seem to be identical to the regular "all" view but it's certainly showing stuff that doesn't "need answers".
- "Needs Answer" should probably have a different name. I don't know what but it seems silly for a subcategory to have the same name as the main category... or just get rid of it and limit the drop down to the three "All, "no answer", and "bounties".
Unless there's a strong interest in viewing only questions that have an answer but one that's not accepted/upvoted, I think it can just be removed in favor of the "all" option, which gets rid of the redundant terminology.
