Since the resource tree isn't showing the individual articles, how would one go about creating internal links between articles? For example, on one article I am discussing templates, and want to link to the article on snippets. Or perhaps I just want to say "in the previous article we discussed thus and so, and in the next article we will discuss something else" with appropriate linkage.
Indeed. Even if the list of articles in the main Articles form showed the IDs of the articles, that wouldn't be much help when editing an article. Perhaps allowing a view-only list of the articles in the Tree?
