That being said, if it is really such that castling is good, the usual way is to discourage moving an uncastled King not by Piece-Square Tables, but by giving a hefty bonus for the possession of castling rights.
This is already part of the development evaluation. And the quality of the pawn shield is part of the king safety evaluation. If it's not castling, it is probably because, as you say, it is not a good idea. While the evaluation function cannot be perfect, ChessV does know what it's doing.
And a final thing which is rather hard. But if you can please add the customizable value for the joker.
I don't know about this. The value of the piece itself cannot directly change, but it would be possible to add a new evaluation function that makes an adjustment to the final score based on the relative values of the joker(s). I will give it some consideration.
