[Unknown Mod][Adventure map] Hero's predefined path favors horizontal and vertical moves first, and hero's path is adjusted to take into account the revealed terrain

[LeHerosInconnu]

The hero's predefined path favors horizontal and vertical moves first, rather than diagonal moves.
It can happen during the game that the hero's movement is stopped by the player before reaching the end of the predefined hero path.
If the hero spends 150 movement points with his first step diagonally, the extra 50 points spent compared to the 100 points spent with a horizontal or vertical first step cannot be recovered later in the hero's movement.

When a hero moves by revealing the adventure map (the Fog of War is removed as the hero moves), the hero's path is adjusted to take into account the revealed terrain.

This is not an option.
This can be implemented directly in fheroes2.
