Highlight moves (like in videos)

Does chess.com intend to add the ability to highlight pieces / squares and show potential moves?

I see this feature in the videos produced by chess.com have some cool capabilities (arrows, square highlighting) like this:

Here's another post with a similar request:

The incentive for this feature is that I would like to help others learn chess, and yes, there is other software that does highlighting very well.  However, I'd rather spend X amount more on chess.com than purchase Y software if possible.

Cool!  I just found out how to do it on Chess.com's analysis boards!!!

Press Ctrl and drag, and it will draw a green arrow, press Ctrl and click a square and it will highlight the square!

Awesome!  Is this in a blog somewhere on Chess.com?

Thanks,

You can also just right click. Right-click on the board to highlight the position, or right-click-and-drag to drag the arrows out. 

I should also mention that it doesn’t just happen on the analysis board. You can do it this to any active games you are watching (i.e. observing). Just that no one else but you will see those marks, obviously.

Can you do this on mobile?
