We recently added a new section to the Kwant website  that contains
links to pieces of code that "extend" Kwant in some cool way. If you've
used Kwant in a way that you feel may be useful to the wider community
make sure to get in touch so that we can add it to the website. The best
way to do that is to make a post to the Kwant development mailing list
 with a link to your code and a few sentences describing what it
enables you to do.
