It would be good to have a function key that allows the user to 'attach all' documents in one movement, rather than having to click each individual check-box.
The same thing goes for adding features to a property or a listing. When setting up a new property, we are currently required to individually click each of the choices under the various 'Features', "Views' and 'Ideal For..' options tabs. Each time we do this, we have to click back into that field and start our search over again. There are way too many clicks, wasting way too much time.
