Reminds me of watching my wife use her computer. I'd help her with something and realize all the little things more regular computer users just put up with. Incorrect focus, focus stealing, windows popping up behind current windows, unclear window styling, invisible scrollbars, moving page elements, unclear instructions, the list goes on and on and on.

Unreal Engine is like this. You stab your toe about a thousand times for the first few months. Eventually you lean to stop pushing the buttons that crash.
