I would recommend very strongly against that, myself. The widgets are difficult to learn, and I've pulled many hairs out over them, but once you get it they are fantastically powerful. For the above, you actually have a few options. I'd recommend you make your own widget class that subclasses list_form, and then you can either: - change the template to do what you want - override update_params in the widget to change the field.label_text for the field in question Or you could make a new field widget that subclasses your field and alter it there. I'm doing both in my case. It seems like a bit of a headache at first, but making your own derived widgets opens up a lot of handy options. There are some good examples coming up on the TosaWidgets site now too. my two cents!
