Apologies, I should have been more specific. "Mature" was a reference to its feature set, not its stability. It runs fine in my setup. I meant things like automatic resolution and scale switching, for example, without having to edit my config file Indeed, I can script that myself, I will. My point is more that if that's the kind of thing I need to do myself, then I'm not paying 60 euro a year.
Having said that: This is simply not mature enough yet to warrant a 60 euro a year subscription, regardless of premium features.
To be clear, I do see the potential and I would actually pay it but this is too early.
