Colour highlight attacked squares

As a learning tool it might be quite good if you could turn on a view to see colour highlighting showing squares attacked by each side's pieces.

I guess it would be too much of cheat in live chess but even if the feature was available during after-match replay and analysis it would be good.

Some times in situations with crowded pawn battles for example it is hard to mentally visualise pathways through the pawns for a king to get involved.

Just something that ocurred to me when watching some educational chess youtubes where the attacked squares are visually highlighted to illustrate vulnerabilities.

If the feature does not exist on chess.com is there any computer chess board (online or offline) that does provide such highlighting?
