[chessx-developer] Chessx Training Mode enhancements

[<dc...@so...>]

Hi Chessx developers,

I would like to suggest two enhancements to the Training Mode.

1.  Add an option to show the *letter of the piece that moves next(i.e.
P,K,Q,R,N,B)* in the square that shows the side which is to move.

2.  Add an option to show *which files, (i.e. abc,de,or fgh) the piece
that moves next is on* in the square that shows the side which is to move.
 The letters, abc, de, or fgh, would easily fit in the square.

Both of these options would reduce the number of candidate moves, and
might make playing through games using the Training Mode more fun.

Of course the option should work if the sides are flipped or if the user
goes backward in the game.

Please let me know if anyone decides to do this.  I would do it myself but
I don't have the time right now.

Thanks,
