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

It is possible to create a comparison of text files, but it is quite laborious. After all, text files need to be compared according to specific parameters, as there are different language versions.
I don't have time for this in the foreseeable future.
But I can tell WiZarDX_576 how to do it.
(it's simple:
1. host: requests text files
2. connected: receives the host's request, opens the text file, sends it to the host (this is done for each required text file)
3. the host receives the text file, compares it with its own, if there are discrepancies, it reports them and sends a message to the connected user.)

So, influenced by watching streams, I added a display of the opponent's timer while waiting for their turn.
But this feature is useless with the turn timer.
Here's an idea: the player waiting for their turn could see the total number of movement points of the opponent's heroes as a percentage. This would be convenient for players and stream viewers.
