GAWLP > documentation questions

To finalize the documentation I need answers to the following:
1. Was it intentional to suppress the value attribute for the searchText and email feature options? It is no longer possible to insert default text using these features. My understanding is that it was intentional since new features (defaultSearchText and defaultEmailText) were created to fix the problem of user-entered text remaining on the page, but need to confirm.
2. For the feature allowEmptySearchText, please give an example of the code to use when it is true and the code when it is false (I can't get it to work so I think I'm typing in something wrong here).
3. Please explain the highlight feature more. Is it actually a configurable feature that we have to add into the page? The current explanation makes it sound like it happens behind the scenes without requiring a line in the newly created page. If it is a configurable feature, please provide an example of the code.
