Also been using nbdev for work projects in past month. So far, it's been a great productivity boost.

I really, really like the specific aspect of testing with nbdev.

Your docs/examples are your tests. The notebook is a natural environment for scaffolding mocks and other things, without having to use a testing framework over top of the unittest objects.

I'm a long-time user of IDEs, and always will be, but if your metric for producing code is just lines of code, nbdev isn't for you. However, if your metric is producing documented, tested code that is maintainable, it's definitely, for me and my team, a big productivity boost.
