What are some useful non-built-in Django tags?

Question

I'm relatively new to Django and I'm trying to build up my toolbox for future projects. In my last project, when a built-in template tag didn't do quite what I needed, I would make a mangled mess of the template to shoe-horn in the feature. I later would find a template tag that would have saved me time and ugly code.

So what are some useful template tags that doesn't come built into Django?

Smart {% if %} template tag

If you've ever found yourself needing more than a test for True, this tag is for you. It supports equality, greater than, and less than operators.

Simple Example

{% block list-products %}
    {% if products|length > 12 %}
        <!-- Code for pagination -->
    {% endif %}

    <!-- Code for displaying 12 products on the page -->

{% endblock %}
