Attack arrows and defense markers per piece
Sometimes you need to zoom in on one piece, the knight that dominates an outpost, or the bishop staring at your king. Chessyi's piece analysis panel lets you highlight individual units with move arrows and attack/defense markers.
Use it to explain tactics to students, or to verify your intuition about which piece is truly active in a cluttered middlegame.
