In the new interface you have replaced tabs across the top of a page with a list on the left. E.g. for the Folder view, you have a list of folders down the left.
That's great, but if the list is long, you may have to scroll down the page to remember what folder you're viewing. Same for tags in Tag view, contexts in Context view, selected search in Search view, etc.
How about putting the name of the selected folder (tag, context, etc) in a header at the top of the page. Also put it in the window title. That way it will be always obvious exactly what list you're viewing.
