It’s good to see so many replies, to bad that I have very low hopes this will be considered as a viable fix. Even here some users thinks it’s waste of time which is of course not.
I should also mention that just scaling down the ui is not the way to go. It’s the easiest way but the worst one. Of course the pulley down is one example where the one hand usage is a place where it shines but there are more places.
The keyboard is one of it, currently operating it with one hand is bad, doing this with two hands in landscape mode is also a pain.
So what’s left is using kind of a dual hand mode in portrait mode but it’s not perfect.
