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

I don't know what's implemented there.

This is very much like you. As usual, you don't know anything, but you expect everything to be handed to you on a silver platter. Maybe we could separate the ones and divide the stack in half into separate buttons, with each button under its respective stack? :D Why cram 100500 different and unnecessary buttons all over the screen?
