The value we see in the app navigation is the following:

The navigation is separated in three broader levels. 1. The first level is everything that is relevant in the moment (Inbox, Next, Away). 2. The second level is to organize everything Idea, Project or Archive. From time perspective mostly related to the next weeks. 3. And the third level is to review your hole system.

After a short time it will feel like walking through different rooms and levels in a building.
