Is there a Node.js feature available in newer versions that you're looking to use?
Nope! But I'm a frontend dev by day so writing in ES6 syntax made me "think" about it. It wasn't that long ago we had to check our Node versions at work either.
@jziggas would you make making an issue on t2-cli to add this? I can also help advise if you want to contribute this addition - it shouldn't be very difficult.
Sure. Hadn't thought about contributing but I will read up a bit on what the necessary changes would be.
