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

Even though some people don't use the keys for transferring the entire army at all, I think they are useful and I want to change/adjust the algorithm, maybe simplify it.
Currently, in HD, the algorithm for selecting a unit to leave behind is as follows:

Very useful and necessary buttons. And the algorithm is generally adequate. You still can't make it fully automatic so that it works 100% according to the player's intention.

There are some questions regarding Shift + Click. By default, it divides the unit in half, but sometimes it creates an incorrect exchange when using Shift for transferring the army. Maybe, is there a way to fix this, or move the function to another key?
