I’ve spent some time working out how to make NP a native app using the Cocoon.js
You can read about it here. https://www.ludei.com/
If you want to see what it is going to look like you can simply download ther launcher app from here
and just load NP as if it was in the browser.
I’ve found on Android, using the webview+ option is much faster than Chrome browser, but on iOS the app is just a little slower that the iOS7 browser.
Anyhow, that was my afternoon.
