Quickform suggestion: replaceElement()

Hi Bertrand and Alexey, I´m currently writing an extension for DB_DataObject that can automagically generate QuickForm objects from auto-generated DataObject classes, which works surprisingly well until now ;-) However, on some occasions it might happen that a user isn´t happy with one of the auto-generated form elements, so that he wants to replace that one element manually. If I just do removeElement() and then addElement() again, the replaced element is now the last in the element list, which can look a little silly with dynamic templates. So I thought, a replaceElement() method would be nice to have in QuickForm, what do you guys think? Regards, Markus
