So, for example, if you have 'Older' collapsed but the rest expanded, it should stay that way unless you change it. My naive interpretation of it is that it should honor how you have the expanded/collapsed state of various sections in Inbox (or other folders with the view) set. There's an Advanced View setting in 'Group By' called 'Expand/collapse defaults.' If it's on 'As last viewed,' what should that do, exactly, for the behavior of the expanded/collapsed state of sections like 'Last Month' and 'Older' in Inbox?
