I was just going to make the same suggestion, it seems strange as it should be such an obvious option to allow the user to configure from a programming point of view.
It would especially be useful for allowing the playback of master games, it's a common training technique to watch master games and it would make it so much simpler if they could be set to playback at a bit of a slower speed so you have time to take in the patterns and nuances going on.
ps. As a platinum member I will be more inclined to continue paying money to chess.com if this little feature was implemented
I've had a request that it should be possible to alter the playback speed of completed games by some increments. In this case, to slow it down some.
Perhaps a user setting to adjust the speed? (+/- .5 second increments?)
Thank you for the consideration.
