Currently, if you toggled open two or three children and you click the refresh button, it collapses everything back to the root document. If you are developing a feature that edits two or three children deep, every time you test something you must refresh and open those children again. I think this is similar to https://feedback.mongodb.com/forums/924283-compass/suggestions/40564825-remember-the-expanded-state-of-object-when-coming but is focused on refreshing the same collection rather than tabs.
