HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

I made another thing to speed up the game.
As you can see in the screenshot, there are two "OK" buttons in the window.
When you click on the right one ([Enter]) - after closing the window, the focus is set on the right hero (usually the right one is the one to whom you passed the turn).
When you click on the left one ([Esc]) - the focus remains on the left hero.

Is such a function in demand?

Making the window with information about the enemy monster static in battle (so that you can see the remaining time of the spell) is easy. But won't this feature be considered cheating for an opponent playing without Hotkeys??
