Survey settings is composed of 2 pages:
1 Survey configs, with tuples (name-value) .e.g. Allow Saves Y/N
2 Survey textes, with survey title, welcome, endmsg.

The first part of settings are set at start of your work with a survey, and rarely fixed later.
The behaviour of a survey is technical choice, with a tendency of no change over time.

The second part is very frequently used, I believe it stays at the same level of questions and aswer, often modified for the same aesthetic or pratic reasons.
