Something very basic that limesurvey is missing is a "Total count" row for each question. This is something that people who look at stats require

For example the screenshot example in the limesurvey documentation at
http://docs.limesurvey.org/Statistics&structure=English+Instructions+for+LimeSurvey
The count will be 6 as indicated by the filter, but would change for multi answer questions.

Also this feature should include the ability to remove the
No answer and the Non Completed rows, without having to filter the questions answers (it could be a global check box "Do not include No answer or Non Completed")
