Take a look at the attached screenshot! Why am I showing it?
One, because it's
Two, because I have absolutely no idea how I got there.
Three, because it shows that a horizontal button layout isn't impossible, see [REQ]
I was testing some changes - unrelated to UI layout - and all of a sudden KUAL changed the button layout like that. All buttons were perfectly functional. But it didn't last. And I don't know how to do it again.
