troffasky: Isn't it the case that 90% of the point of RouterOS and its management tools is to wrap all the underlying nonsense in a consistent management interface? If you want to twiddle with text files, install OpenWRT. The corollary of that is that every parameter has to be available so that you don't need to get up to your nuts in text files.
It is possible that you might have misunderstood my point as the intention was in no way to discredit the use of WinBox.
Rather, this will offer the ability to introduce new and complex configurations using the CLI without depending on the development pace of WinBox. As you've probably noticed by now, this is an already established way of working when it comes to new features in RoS just like Containers, ROSE and so forth.
However in general, just because you have access to a GUI doesn't make it more easy to configure ZeroTier, or any other feature for that matter, because you still have to understand the meaning of all the parameters just like with the rest of RoS.
