This is now a substantial improvement! The last two (or three) steps in the filtering/removing (I believe) are these:

1. When "unfiltering" after the queue is empty, right now the Segment filter is removed but the question filter text remains. Removing the question filter text and clearing that text input to "" would be great.

2. It would really help to have the option to filter complete question numbers. By this, I mean that I want to be able to get just question 5 and not have to contend with 51, 53 55 etc. when I want just 5. My suggestion for this would be adding to the question filter logic a backslash. If I type 5, it should keep acting as it does now but if I type "5" it filters ONLY questions named EXACTLY "5" ... this probably would mean that backslash needs to be NOT a permitted character in question numbers.

3. (Bonus but nice) When I click on "5" in the question number column of the responses queue, it should filter BOTH the question number to "5" AND the Segment # selector to whatever segment that particular question 5 is from. I will never want ALL the question 5s when I click that nor will I ever want question 50, so this is the preferred behavior.
