Mod requests (orders).

These are all workarounds. I need a function. I could also try to figure out where and on what each player starts by trial and error.
If you can't make such a mod, just say so. What's the point of these suggestions?

Good advice can also solve some problems. And it's still better than complete silence on the forum.

But is it still possible? I think such a mod would be useful not only to me.

If the AI's turn takes place on its territory, where there is a fog of war, we will still see a black screen. And in Multiplayer, it might be fairer if players don't see what's happening during their opponent's turn.

If this "feature" is implemented at the exe level, only those who can (and are willing) to modify this exe file can solve the problem.

I'll take a look at the xdb set of files for windows and other things, from which the turn waiting screens are assembled. Perhaps the single-player version differs from its multiplayer counterpart by just one simple black insert, which will be easy to remove.
