Yes it would be great to have such a repo whee to find example and share forms and copy/paste blocks of questions.
It was discussed it a little during the TAB application last september. And you should find volunteers to feed such a repo
From my experience, a lot of people have forms to share. What a resource it could be to save time, not rebuilding the wheel, and go further.
First, share best practices and a complete form template, with all columns well ordered should help.
