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

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>

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

original issue: https://github.com/facebook/react-native/issues/5079 it's an opportunity for libs to decide an implementation based on if the lib is available or not. For instance, it's used in seedrandom: https://github.com/davidbau/seedrandom/issues/31

When using any kind of zIndex value with position:'absolute', dynamic components (views in an array for example), will fall out of place or completely disappear when changing its position. Related github issue: https://github.com/facebook/react-native/issues/8968

When prepending stuff to FlatLists or SectionLists or any VirtualisedList for that matter, the list re-indexes it's children, and we end up with a wrong child showing up (The new index now refers to a totally different child, so it's as if the list scrolls to something else than the child we were on before the prepend). https://github.com/facebook/react-native/issues/25239#issuecomment-521194810

I am using TextInput with without height limitation. Scrolling becomes one of the problems. In order to scroll to the line I am typing I have to know the coordinates of the cursor and scroll to there. I am currently using the solution given at the following site ( https://medium.com/@p9alisand/how-to-get-textinput-cursor-position-in-react-native-0-49-1845aee40e9b ). Since it is hard to maintain, I am wondering if you guys can add similar feature to react native library? Thanks you so much.

The feature could be implemented in textVerticalAlign: sup and textVerticalAlign: sub style rules, following vertical-align CSS rule
