Just tried the latest patch and I love the sliding. Haven't tried it on clay yet, to see if there's much difference between the courts, but so far looking great Manu. I know there're no sounds of squeaking shoes as the player slides on hard courts yet, but I'm sure that's not the priority right now and it'll come when it's ready.
My only suggestion for the sliding is when sliding to the backhand side, the player should reach the ball, slice it back in play, and turn the opposite way. I'll link a video if you need it Manu, but it's a move done by a lot by Rafa and Novak.
