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

I would like to know how feasible it would be to add a function to the online lobby, in addition to the blacklist, to "block a user," so that they cannot only write but also join a created game (ideally, they would also be kicked out if they have already joined!). And, if possible, make the password for a created game the same as the in-game password, with the option to hide it with asterisks. P.S. I'd also like to bring up an old question: why has the numeric keypad stopped working in the in-game chat (at least in the castle trading window)?
