The vertical layout feels very unusual; I think it would be better to keep the horizontal arrangement and remove the small transfer buttons next to each stack. Instead, the images could be made larger. I also think it would be helpful to bind the artifact and troop exchange between heroes to keyboard buttons, like the "lighter" key. As for the additional information, it's very convenient; you won't have to count at the beginning of the game, and it doesn't really feel like cheating because you can still calculate everything manually.
