How about adding the piece names as tooltips when we hold the mouse over the shogi pieces? So when I hold the mouse over a pawn, a tooltip pops up saying "Pawn".
I thought about it because I have a hard time distinguishing some of the captured pieces, since they are smaller. But it would be useful on the pieces on the board too, for people switching from westernized to traditional pieces.

This could perhaps be optional, and it's also possible for people to turn of tooltips in their browser (well at least in my browser) if they don't like them.
