Two small requests

a. Allow developers to add custom fields in your question submission form.
b.Allow developers to handle the custom field which gets posted in the submission form.

For a : In template file templates/question-submit-form.php, you already have provided two useful hooks “dwqa_before/after_question_submit_form”, it would be really great if you can add them inside the Form tag or create new hook dwqa_before_question_submit_button just before the submit button.

For b : In handle.php function submit_question, after the new question is inserted and before redirection to the new quesiton, can you add an action hook and pass the question id argument,
do_action(‘dwqa_after_insert_question’,$new_question);

Both requests would really help in adding custom fields to the question format which can be later filtered out using the stored meta values.
