Nice to hear. I'll wait some time before I merge this into master: more tests needs to be written and I'll wait for you to give feedback after some time....

Well, this branch should - as it's name suggest - retain value of attr column (and set to current active language on object creation). So it's something wrong with the...

Example is correct and exactly as it should be. Generally, this branch makes sure that no action change the `attr` column value. Except for object creation, when `attr` gets value...

All you want is to keep it null or empty string? I think we could add some settings flag that control whether original column is set at object creation time.

That's the problem. `TreeManager` is used and not patched by modeltranslation. Are you sure that `Branch` model is registered for translation? Try to set `MODELTRANSLATION_DEBUG = True` in settings and...

Well, I created test case for pickling a model with custom Manager using custom Queryset - and it's passing. Can you provide more details about Python, Django and MT versions?...

`TypeError: 'title_en'` sounds like modeltranslation hasn't been triggered (imported). How is your script run? Does it perform Django `setup()`, and is modeltranslation in `INSTALLED_APPS`? Moreover, is English an active language...

Leiningen-like hints like `^:replace` would be great and sufficient, and it will allow to either merge or replace (or undefine) each option. And since task options take precedence (override) edn...
