Q1. It looks that most convenient way of developing Rails Views is using form helpers when developing forms and partials.
On the other hand one can develop much richer HTML5 pages/mockups using WYSIWYG tools like CKEditor, Dojo/IBM Maqetta, etc.
How one can continue with Rails having already developed Web site mockups?
Q2. Up to my findings, Ajax can be automatically fired using :remote=>true but just in link_to and form_for helpers.
