- "this" always means the current chain scope inside a DSL
- addFutureAction callbacks now take ($window, $document, done)
- $document has a special method elements() that uses the currently selected nodes in the document as defined by using() statements.
- $document.elements() allows placeholder insertion into selectors to make them more readable.
ex. $document.elements('input[name="$1"]', myVar) will substitute the value of myVar for $1 in the selector. Subsequent arguments are $2 and so on.
- $document.elements() results have a special method trigger(event) which should be used to events. This method implements some hacks to make sure browser UI controls update and the correct angular events fire.
- futures now allow custom formatting. By default any chain that results in a future can use toJson() or fromJson() to convert the future value to and from json. A custom parser can be provided with parsedWith(fn) where fn is a callback(value) that must return the parsed result.
Note: The entire widgets.html UI is now able to be controlled and asserted through DSL statements!!! Victory! :)
