@zhongneu thank you for taking a stab at bringing that feature to life
again!
:+1: for screenshots, but could you please also updated PR description a
bit, explaining how exactly the hierarchy is formed? Like how to create a
nested structure of notebooks, and if there are any changes in how notes are
persisted.
This, as well as screenshots, usually helps communicating the value of the
feature and gauge people's the interest.
Also please feel free to assign
[ZEPPELIN-209](https://issues.apache.org/jira/browse/ZEPPELIN-209) to yourself,
so it's not get lost on the release.
