Request that application open to list of notes, rather than to most recently edited
When the application opens, it displays the editing layout set with the most recently edited note, even if editing of the particular note only occurred external to the application.
Such behavior is not expected based on common design patterns.
The closest similarity would be session management, but a session normally would include data not explicitly saved to the resources, and would not include within the session a resource edited externally.
For comparison, the other Nextcloud applications, including mail, contacts, bookmarks, and so on, open to main lists, not particular resources.
Please consider setting the notes list to the default display when opening the application.
If some users prefer the current behavior, the perhaps it may be given as a user preference.
My observations are from running Notes 4.8.1 on server 27.0.2.
