Why is the Wiki style guide Status > Dashboard but the webgui is Status / Dashboard ?? Just curious.
All of the docs everywhere have used ">" for quite a long time, to indicate Menu Name > Menu Item, in this case the breadcrumb trail is using more of a "directory path" style which doesn't always translate to Menu Name / Menu Item since there are also tab names and so on that go deeper than the menu.
So the ">" is a direction to the user, while the "/" is a visual depiction of the structure. The "/" could be changed to a ">" but I'm not sure it really helps or hurts anything significantly enough at this point to do so.
