I arrange my notebooks in stacks, for example I have a stack called tasks, and within that stack I have Work Tasks, Home Tasks, etc as separate notebooks.
In the desktop versions of EN you can see all notes in a stack by selecting that stack. So I can see all my tasks by selecting the task stack.
However in the iOS apps you have to select individual notebooks within a stack.
It would be great, for consistency across the versions, and functionality if this way of working could be added.
Should be fairly easy as essentially that’s what the ‘all notes’ does but for all notes not just a specific stack
