Yeah, I’ve seen this one (it is relatively recent). Not doing react-native at the moment but the JSX and syntax highlighting part does work for react.
On a completely different topic, I still find it a bit awkward that Code doesn’t support proper tabs. Some may argue that you don’t really need them but it has been the way I work for many years so it’s difficult to transition to the “Working files” approach. With that being said, I think Code is awesome and still use it on regular basis for ng2 apps and nodejs projects (mainly due to its amazing debugger)
