 Most projects that are using both Redux and React Navigation don't need this library. And passing `navigation` to the root navigator means that you will have to handle state persistance and `BackHandler` behavior yourself. However, there are some things this library makes easier:
 
-1. It's possible to implement [custom actions](https://github.com/Ashoat/squadcal/blob/4ce900481bbfd1681d568edc669b66b1ae9555f0/native/navigation/navigation-setup.js#L384-L395), allowing you to manipulate the navigation state in ways that aren't possible with the stock React Navigation actions. Though it's possible to implement [custom routers](https://reactnavigation.org/docs/en/custom-routers.html) in React Navigation to do this, it's arguably cleaner to via Redux. (If you want animations to run on your action, [make sure](https://github.com/Ashoat/squadcal/blob/4ce900481bbfd1681d568edc669b66b1ae9555f0/native/navigation/navigation-setup.js#L633) to set `isTransitioning` to true!)

 2. This library allows the user to customize the persistance of their navigation state. For instance, you could choose to persist your navigation state in encrypted storage. Most users don't need this, as there are no practical downsides to handling persistance of navigation state and Redux state separately. Note that stock React Navigation supports some basic degree of [persistance customization](https://reactnavigation.org/docs/en/state-persistence.html).
 3. You can implement [custom reducer behavior](https://github.com/Ashoat/squadcal/blob/4ce900481bbfd1681d568edc669b66b1ae9555f0/native/navigation/navigation-setup.js#L341-L352) to validate state and maintain consistency between navigation state and other application state. This is again possible with custom routers, but likely cleaner to implement without, especially in the context of an existing Redux setup.
