When soloing one or more channel, all other channel mute buttons lit up. This is not the appropriate behaviour. Their state should stay the same, just like in the edit- and mix windows. There is no reason why those mute buttons lit up, as it is already indicated that tracks are soloed, by their solo buttons being lit, as well as by the blinking clear solo button.
If you want to change the auto mode of a channel twice in a row, you have to double tap instead of single tap the corresponding sel button twice instead of once 95% of the time. In combination with the lack of proper visual feedback on the s3 this is very annoying.
