Problem: This isn’t really a problem that necessary harms users, just a suggestion for something that would help.
Proposed solution: For every test wiki, it will be possible to choose an article, then get a graph with arrows showing what articles the specified article links to, and what articles the linked articles link to. Probably a maximum of 3-5 jumps.
Who would benefit: Editors in test wikis in the incubator.
More comments: Will be useful to estimate how much content the test wiki has and if it uses wikilinks correctly.
