Yes, it's basic. Because scaffolding is basic. It's also not meant for production use.
Second, people like the scaffolding because it builds forms for them :)
I just released a gem called scaffold_form_generator that does the form generation part of scaffolding (no controller, no model, just the form). It's really meant for use in Rails 2.0 apps though since it uses RESTful routing and the new .html.erb syntax for forms.
I prefer checkboxes for booleans... it's quicker and just makes more sense from a usability standpoint.
<%=check_box :model, :active %>
When you generate a form with scaffold_form_generator, that's what you get. :)
If you're looking for something more advanced than scaffolding, look at ActiveScaffold or Streamlined, two very nice projects that take scaffolding to a whole new level, one that could be used in production (though I still think you should code your own user interfaces, but I'm an HTML guy at heart.)
