Show HN: Normalized File Field for Django

I'm tired of having to treat FileField in forms in a special way. And it's very tricky to get it to behave nicely, with all combinations of form validation and the "Clear" checkbox...

So I made an app that takes care of it: https://github.com/frnhr/django-normalized-filefield

It is still somewhat in the "proof of concept" phase, but usable IMO.

Any thoughts on what the ideal file input should behave like?
