Ask HN: Better Jupyter code completion?

I've been consistently hitting a wall with Jupyter's autocomplete and docstrings capabilities, especially when working with pandas:

* No autocomplete when kernel is busy

* No docstrings or autocomplete for dot-calls (e.g. `Series.str.contains`)

So I end up having a devdocs.io tab open for just those two situations.

Is anyone aware of efforts to lighten this situation? Say, plug-ins, or integration to other services that would overhaul the default results from Jupyter's <Tab> and <Shift-Tab>? Thanks.
