idea to implement drawing in mobile

So I’ve been playing on chess.com since the summer, I’ve become hooked and I love the site! I’ve been playing on the laptop mostly and I really like the ability to draw arrows to keep track of your thoughts. For Christmas I got an iPad, so I’m happy that I get to play on the app, and I don’t have to be at the computer to play now!

I’ve noticed that at the moment you can’t draw arrows on the app, and I was wondering if there were any intentions to add this feature? I was thinking that it would be nice if you could hold one finger down and draw the arrow with the other finger on touchscreen. I understand that this may be awkward on phones and smaller devices, but perhaps there could be an option to turn it on so if you are on a big enough screen, you could do it if you wanted to! I’d be interested to hear your thoughts.
