All look good in my eyes except the third. I'd probably buy the first one if I decided to buy one, as it looks the best in my opinion. Very hard choice though.
is that request same like primedice has now? i mean about a small audio sound, i don't think it's best idea
A option to disable it/enable it wouldn't have any harm, and I don't think it would be very hard to code. As long as it's an option, and only an option, all players should be fine with it.
