    * django-debug-toolbar
    * django-secure
    * django-celery
    * django_compressor

    * render_to - seems to be roughly equivalent to django.shortcuts.render
    * signals decorator - now in core[1] (since 1.3)
    * ajax_response - seems useful, though might make sense to check request.is_ajax[2]
    * autostrip - hmm, seems oddly edge case-y, I definitely wouldn't apply it to all my forms
    * get_object_or_None - nifty 
    * AutoOneToOneField - assumes the related model is valid with only the FK filled in, which seems fairly unlikely in many OneToOne cases.  I'm not sure if this was proposed to core, but I'd think it would need some sort of default= fillin feature to be more generally useful.
    * JSONField - soo many competing and variously featureful implementations. This has been discussed a few times; it seems fairly easy to implement and hard to gain consensus. I wish we could get it in core, but the juice doesn't seem worth the squeeze.
    * get_config - I don't think I understand the purpose of this, unless you're just trying to be more intention-revealing than getattr(settings, ...)
    * HttpResponseReload - nifty
    * StaticServer - I don't think I understand why you wouldn't want to config urls.py instead.
