Challenges in creating wiki via Coda - from navigation point of view

We are trying to create wiki for whole org with multiple folders for each BU where they can manage each doc. But at an org wide view, it is difficult to create a simple navigation across multiple docs and folders which allows people to easily access docs in their respective folders though still able to see all of them at same time. I am looking for an experience which gives meets following requirements:

  • Any internal user in company can view and navigate docs in a structured manner (imagine there are 100+ docs) like in a website while Editors and Doc makers can still control and work in respective folders their individual docs without worrying about other docs and folders easily.
