It is extremely important that the digging ability functions properly, even if the hero has only 2500 gold in the treasury (currently, it only works with 5000).

This is indeed very important, but the difficulty lies in the fact that if you have less than 2500 after purchasing a hero (i.e., less than 5000 at the beginning of the process), you won't be able to see the army of the next hero that appears. Moreover, since Heroes of Might and Magic I doesn't have secondary skills, the starting army is the main asset of the horsemen.

Implement the ability to scout in 20 castles (very useful on large maps), or at least in 10.

This function is easier to implement: the city number = the number of times the "T" key is pressed (if saving with the selected hero), or the number of times the "T" key is pressed - 1.
