Github user sergeymazin commented on the issue: https://github.com/apache/zeppelin/pull/2120 Issue we are facing is when somebody else is adding/renaming/deleting any other notebook, unsaved text in current notebook is lost.

This makes Zeppelin unusable when working in multitenant mode once somebody starts importing/renaming notebooks.
