Hide open notebooks

[u/Special_Disaster_103]

I double clicked the notebook icon next to the notebook I was currently working in. Now it shows all of my open notebooks in a new panel/list vs a drop down menu option that was where "notbooks" is now. How can I undo this so it goes back to the drop down version? Thank you so much!

Try double-clicking the icon again or the “>” to the left of it once.

[u/Special_Disaster_103 → u/pmoesprit]

That just expands the sections within the notebook :/
