[MOD] LEGACY CLASSIC 1.0 Standard high-quality interface for HoMM V 3.1

You completed one of the three installation steps, and that's why the issues mentioned occurred.
This applies to everything except the logo in the menu and the tooltip issue for you.

And why aren't you playing with your own mod?

Regarding the tooltip in battle, I understood that you mean the window itself moved to the right. And what problems does it cause being further to the right?

I'm simply not interested in the other two installation steps, only the interface. But, as it turned out, the interface-only mod (800+ MB) is not self-sufficient, and it requires a mod for additional campaigns and mod-fixes. I don't understand why files that don't belong to the main mod are embedded in it, but are needed in the mod for all campaigns, which is distributed separately? Because of this, the campaign selection menu of the main game displays incorrectly.

Alright, I guess I just stopped understanding all of this. So interdependent modular mods are normal, but an interface mod needs non-interface mods to work properly.

I looked at what the interface mod offers without my own and other mods.

The window itself didn't move to the right — the skill and ability icons in those windows became larger, while the position remained the same, and the right side of the skills and abilities isn't displayed, so it seems like the icons shifted to the right.
