New template manager, introduced in 4.0.0, has breadcrumb navigation. This is basically great, but it is missing some kind of separators between buttons representing directories. Adding them would make breadcrumbs easier to recognize and use. Most common separators are: > → /
Thanks for reporting. Can't find any duplicate and I think this'll indeed be a visual enhancement. Therefore I mark this as NEW.
New template manager in 5.2 no longer has breadcrumbs.
