Image in eileenmcnaughton's github results in page not found
I followed the link https://github.com/eileenmcnaughton/org.civicrm.module.cividiscount/blob/extended_filters/docs/images/advancedFilters.jpg but no image is shown, just 404
On another note, re: Nice to have 'Give some control over the placement of the discount code text field on the form.' I added an extension template (Register.extra.tpl) using jquery to 'place' discount code box after price total on event Registration form, I can attach or submit as a patch. A user would need to find an element in the form if they want to change it.
