Hi,
It would be useful to offer, at least during the initial insertion phase, the possibility to insert a big JSON. This ability integrated in the widget would be fabolousI trivially tried to modify the widget with a forms.Textarea widget overriding the form's init method (if no instance passed to it change the widget ) but i had this exception after i save the data:

Unfortunately I do not have enough time to work on it, so this time I will use a fixture
Thanks
