We should be able to create custom animation by switching from a tab to another

Many times we need to be able to retrieve data from a screen we pushed into the stack. To achieve this we need to use navigation.navigate(), wich force as to specify which is the screen we are coming back to. Since we have goBack() method to not worry wich is the previous screen, makes sense to be able to pass in some parameters into it.

Now, can not add gradient color like LinearGradient to theme background color. I would like to use it. How about that?

i have 3 stack const OnboardingStack = StackNavigator({ OnboardingOne: { screen: OnboardingOne }, OnboardingTwo: { screen: OnboardingTwo }, ... }); const TabsStack = TabNavigator({ TabOne: { screen: TabOne }, TabTwo: { screen: TabTwo }, ... }); const Root = StackNavigator({ Onboarding: { screen: OnboardingStack }, Tabs: { screen: TabsStack }, }); When I was on the OnboardingOne screen, I navigated to the TabOne screen and I got an error: 'Error: No routes defined for the main Tab. Must be one of 'OnboardingOne', 'OnboardingTwo'. I hope you can help me find the solution to this problem

On tablet in portrait mode it should be awesome to have a tab bar at the bottom and a 1/3 pane left with a list container and at the right side of this pane a 2/3 pane with the detail view of the selection of the list item from the 1/3 part. On tablet in landscape mode, the tab bar should be better aligned at the left of the screen, and still having the 1/3 + 2/3 screen pane ratio. Actually, to be more clear it is a master(list) + detail layout.

Connected to https://github.com/react-navigation/react-navigation/pull/2721 It appears that the drawer items don't allow this param to be passed to it, but probably should allow this as the drawer can cause some issues when the font is scaled massively.

It would be good to have in theming mechanism the ability to override the default system font families. Right now you have to override on each Navigator or Screen level.

shrink/grow header when scrolling down/up

being able to have a permanent drawer is great, but I'd love to provide a way to still open/close the drawer programmatically in some cases. For example: when a user of an app is writing a post focus on the writing screen and remove the sidebar as a distraction. give the users an ability to hide or show the navigation as needed via an icon (see the Bear notes app)
