Headless JS is very useful for running background jobs and it would be nice if it worked for iOS as well. It is already supported for Android: https://facebook.github.io/react-native/releases/next/docs/headless-js-android.html

I heard about CSS Grid Layout "Display: grid" So I wonder if React Native could support it

If I render an SVG image with `<Image source={{uri: 'https://productpains.com/img/user-placeholder.svg'}} />`, nothing renders and I don't get any error message.

This would increase the flexibility developers have regarding automated scrolling, e.g. a 1,000 item list should not be scrolled to the end at the same speed as a 10 item list does. If you'd like I would add a PR for this feature :)

It would be great to have a completion callback to execute something after the ScrollView has finished scrolling from a scrollTo call.

See: https://github.com/facebook/react-native/issues/641 This is a very common use case!

On Android, there is TextView's textIsSelectable. On iOS, there is UITextView's selectable. These allow one to click-and-hold to select text in a non-editable text view. It would be nice to expose this feature through React-Native's <Text>

React Native start to be mature enough to think about adding the ability to place, executed in parallel, some controller's scripts in different threads. The one and only bottle neck of React Native is the slowing performance on view building and animations due to the single Javascript thread. We see appearing here and there different node modules that could be merge into React Native core. I specifically think about: - for the workers: https://github.com/devfd/react-native-workers - Hamster for the multithreading engine: http://www.hamsters.io Starting developing on that direction makes huge changes in the app. If those libs were included in Core, there's maybe a way to start threads transparently by placing specific markers at the head of the JS Classes? React-Native is awesome and have all to be the next cross platform language for web and mobile. But in the near future, when the applications will be complex enough, the criticism will rapidly comes from the lack of speed and smooth transition that make all the difference between an 100% Native App and a 80% Native React-Native App...

I haven't seen any mention on the ability to create Android home screen widgets with react-native. Are there any plans for it? Is this something to be included in core to include or should the community jump on it?

(Pan)Responders inside a ScrollView are often stolen from JS because the scrollview is implemented on the native thread. This is a tricky thing to fix but it makes somethings difficult to implement, such as a vertical slider inside a scrollview.
