It would be useful to be able to choose which form element that is activated by defaut when opening a form. As an example, I have a form with an autocomplete as the second form element, while the first element is a check group. The check group is an optional filter for the auto complete query; hence it's not required.
The user should be able to start typing in the auto complete field without having to click on it by default. This only works if the autocomplete is the first form element as seen in the pictures:
Choosing the default active form element independently of form element order should be possible.
