I'll do my best to answer any questions here.
How do you add traditional django apps to the admin? e.g. To get list view and edit forms for regular objects (like you have under "settings" in the admin for Users).
Apologies if it's in the docs but I couldn't see it.
Congrats on the milestone!
Have a look at the register_admin_menu_item hook - http://docs.wagtail.io/en/v1.0/reference/hooks.html#register...
https://groups.google.com/d/msg/wagtail/gootoMvXV8s/yxebbY1Z... has a working example.
- nice UI/UX
- nice features (revisions, preview, choosers)
- pages are easy to extend
- custom apps can be integrated easily by using admin hooks
- good code and documentation
Recently started on a complex project, and we are using some ideas from Wagtail :)
This allows Wagtail users to swap in alternative rich text editors, e.g. https://github.com/isotoma/wagtailtinymce
