That's configurable. It is probably a DottedObjectName
Bookstore (https://pypi.python.org/pypi/bookstore) is an alternative backend that 
store notebook on RackSpace (and allow versioning)

If by right away you mean list all ipynb in subfolder, it can be problematic.
Still nothing prevent you to do that.

Yes it is reasonable, and we have plan to have a more advanced dashboard. 
The current handler should be TreeHandler in IPython/html/tree/handler.py

Session Api already exposes modified dates act, you can read more here :
https://github.com/ipython/ipython/wiki/IPEP-16%3A-Notebook-multi-directory-dashboard-and-URL-mapping

The problem is that we have no way (yet) to send configuration to the Javascript Side, even if we would like to. 
Also we would like to avoid reinventing the wheel and use a pre-existing javascript library to handle the browsing client-side.

We in particular also want the ability to chose between different kernel when you start a notebook. 
So we are moving slowly  in this direction. 

If you start anything, I would suggest for you to contact Zach Sailer that wrote most part of the REST api 
and have somewhere a Draft Branch of UI where you can open folders, and order things IIRC.
