1) The similarity is with "django admin" specifically (not django). The way i saw this was: "if you have models setup with django, django-admin gives you a admin UI for the data without any setup", with subzero "if you have a database (with any schema), subzero gives you an UI for the data without any setup" and both of these systems can be customized with code. Another way to put it: you have your db, you point subzero to it, and you get the UI linked here, no configuration needed, and if desired, it can be customized to any degree
2) actually the overview of the docs is a bit old, it was written some months ago when there was no UI (just the backend stuff) so the positioning changed a bit. While the copy on the homepage was indeed intended for "managers/CTOs" it should have certainly made sense to a developer too so i have to fix that somehow.
Thank you very much for the feedback, really valuable.
