What’s your favorite Django app?

I still believe South should be included in Django itself, but the South devs wanted to keep it as a separate app.<p>I remember when I first started learning Django. You follow the tutorial, write your models. Then you start playing about and want to add an extra field to a model and....oh wait, I need to either add it manually to the database or use a 3rd party app to do it.<p>To my mind it's part of the workflow as you build an app.

Back when I first started looking at Django, the "apps" concept looked really promising. That you'd never need to worry about writing a comments-system again, because there would be a comments-app. That you don't need to integrate your main app with your blog and your CMS, because they'd just be separate apps that you'd drop in and forget about.<p>But the mentioned apps .. aren't. They are tools, plug-ins and libraries. What a shame.

I don't know... Schema migration is rare and something I want complete control over while the debug toolbar is something I use constantly. I definitely would have submitted a vote for the toolbar.

I hope django.contrib moves forward in the right direction and these makes these apps reusable

my fav is probably sorl.thumbnail, followed by template_utils
