@khalidhuseynov I tested and works well in usual cases. However,
1. Set `Persist on note commits`
2. Execute paragraph
3. Stop Zeppelin without committing.
**In this case, The paragraph which was executed is not saved.** But users
normally expect all their changes will be saved. What do you think of?
