ODK Survey -- widget suggestions

[GoogleCodeExporter]

Great work done on ODK build! I have some suggestions for making this tool even 
more powerful and able to manage complex surveys. I don't know if some these 
suggestions are possible or already supported.
1) Option for randomizing list of answers for a question.
2) Option for randomizing group of questions.
3) Option for number of answers allowed in multiple questions.
Example:
Q1: Choose the two most important reasons from the following list?

4) Option for exclusive answers in multiple questions (answers like "Don't 
know" or "None of the above" that can only be selected alone).
5) Option for terminating the interview based on the answers given in a 
question.
6) Use of "go to" or "jump" to another question if a rule is satisfied.
7) Option for skipping or showing only answers given in previous question 
(apply for questions with the same list of answers)
Example 1:
Q1: Which countries have you ever visited?
Q2: Which of these did you like the most? (only selection between countries the 
respondent visited)

Example 2:
Q1: Which is your favourite colour?
Q2: What other colours do you like? (favourite colour must be skipped in Q2)

Thank you in advance.

I second that. Having an option to randomize group of questions will eliminate 
the possibility of biasing during interviews.
