"HW rulez" mod (add-on) for HoMM3.

Is it possible to enable sound during the opponent's turn when the sound is turned off?

Did you mean when the turn is passed? Or did you not notice that different sounds play during the opponent's turn? It is not possible for a regular user to remove some sounds and leave others in the game. And yes, this has already been suggested.

It would also be very good to have a message log. You go to smoke, the opponent writes something, you come back, and the message is gone. What did they write? Why did they leave, for example?

And it would be even better not to use the in-game chat when there is always a messenger available.

Automatically create two corresponding images of the entire map in the save folder every time you view the Air/Earth map.

This has already been suggested.

A calculator in the late game????

I don't always one-shot every stack in the late game; sometimes I need to calculate before the attack, based on the parameters. And sometimes I don't have time to create a table for Demonology. It's not that useful, but it requires very little effort. And a hotkey for physical damage - it seems like a small thing, but it improves usability. In general, I understand - you didn't like it.
