I would really like to see a UI scaling feature implemented in to the game. Right now in the game if I'd like to play in my 4K screen size it's very had to see my cards in hand. Which is a bummer because the game looks really neat in high resolutions. Please, please, add this into the game. It's very simple to do and will make things look a ton better.
For people who don't know what I am talking about... The UI, User interface, is how the size of your cards or health and mana change with different screen resolutions. The small the screen the bigger they are.
