Okay, great, found it.
It's a bit confusing though... There seem to be three places for 'Settings', for Mac here at least: the sidebar, the top screen bar, and the Extra > Addons > Preferences...
Now that I found the sounds, I have some more questions:
-Can I disable the sound for when I end my turn/begin my turn/run out of time? i.e. only play the sound when the status of a game goes to a 'green dot'
-Can I play an extra sound (maybe even one that can be different from the other), when the Early Warning Time in a turn is reached?
-Right now a rotating loading sign is showed every time the script Reloads. This puts the name of the user and the time remaining a bit to the left and back each <Reload Time>. This is not calm, so could there possibly be another picture when it's not reloading? If you understand what I mean.
Anyway, I just played a couple simultaneous speedgames just now. It truly works like a charm
This will greatly
reduce the speedgameturns I miss
