What functionality is missing? What is unsatisfying with the current situation?

I adore Breadcrumbs and want them on every article in my world, by default. I spend a great deal of time going through each (of the now 600+) article(s) to individually add Breadcrumbs. I would like to save time and tedium by bulk editing articles to add and/or remove Breadcrumbs from them all.   It would be truly wonderful and help a lot if there was a bulk edit option to enable or disable Breadcrumbs on every article in a World, or in a major folder section of a world, such as within the Encyclopedia and within the Atlas overall categories.   It would also help a lot if there was a checkbox within Athena / the Articles & Categories management view page so that as each article showed up, in the medium expansion or maximum expansion views, it was as simple as checking a checkbox to add Breadcrumbs to this article, or to remove them from it.   It could help to have the Breadcrumbs default to the first line, and/or the last line, of content on each article, so their position is consistent across articles.  

How does this feature request address the current situation?

It would make the process of adding and removing Breadcrumbs instantaneous, or at least quite quick and easy, from the Articles and Categories views / Athena.  

What are other uses for this feature request?

It would save time and UI space, create more uniformity and ease of navigation for viewers across a World, and inform many users who might not yet be aware of the lovely magic and organizational wonder of Breadcrumbs to their existence and uses, by the existenceand visibility of the new UI options.
