Feel free to add feature request to Github. Our first priority was to support all original widgets, we added just few examples on 3rd parties, but now we will focus on integrating and supporting most popular 3rd party packages - like model translation, django-hvad, mptt, etc.

Actually mptt tree package integration example is already added: http://djangosuit.com/admin/integrations/category/ It doesn't do some automatic sorting magic, but this is in our future plans.
