1. Yes, we are working on Windows tutorials at the moment and more detailed writeups such as how we got the F8 App from Facebook to run on RN for UWP. We've made a lot of strides lately with our React-Native CLI integration so you can do `react-native windows` and `react-native run-windows` which allows you to build and run your applications without requiring you to fire up Visual Studio.
2. We are definitely working on the examples to make sure they work out of the box with our run-windows command and will make sure that's done ASAP.
3. Yes, that's the intention to have a Hello Windows module. Right now we have a little sample that shows how to make custom controls and modules such as here: https://github.com/rozele/rn-tr23 with a map control but we will move a few to our GitHub organization to show you how its done.
4. With the React-CLI and run-windows, you should not need full Visual Studio running unless you are deploying to a device or emulator. If you are having issues with that, please file an issue and we'll get to it as soon as possible.
Unrelated: We are open to prettier templates but currently we are using the standard XAML templates which come with UWP so they have the look and feel of a common UWP app.
We're also looking at the list of the most popular React Native modules and ensuring that they work with React Native for UWP.
