Idea: Preloading

[Karsens]

Hi, this is not really an issue but more of an idea. When you navigate to a new screen for the first time, the component will be mounted and rendered. But then it stays in the background, also if you leave the page. I know this because the second time (going back to the screen), it is much faster! This is certainly the case if there are some remote images on the page.

I care very much about the UX and it's not nice if the user sees images being loaded. That's why I was thinking... what if you could already mount and render the page before going there? Then the first time experience would be exactly the same as a second time experience and would generally improve the apps experience.

instead of this.props.navigation.navigate(options) we need something like this.props.navigation.preload(options).

I don't really know much about how this would and could work behind the scenes, so I just post it here. I'm very curious if this is even possible and easy to implement or very hard.
