Requested feature for mobile chess.com

Hello I want a feature that if you double tap any square or chess pieces you can put the arrow anywhere and the you single tap to put the arrow (only on Android and apple tablets and smartphones) and this is not a bug I want to request a feature.

Why not the chat feature

Arrows for mobile too... its very helpful in calculating

Okay, but how would you unselect a chess piece?

best way for arrows would be to have a button that toggles "arrow mode" so that you could make arrows by simply pressing on 2 squares and, after you press the button again, the arrows disapear and you can play normally again
