It would be nice to see more options in regards to the sound effects. As of right now, all you can do is turn them on or off. They're quite loud, but there's no option to adjust volume. I could just adjust volume on my computer, but I also like to listen to music while playing. Every time I get a notification it drowns out the music.
In addition, since I usually do flash bets, I get a notification of the flash bet ending every 2-5 seconds. The only reason I have sound on is so I can easily know when someone likes my comment or responds to it, and when the bonus duck flies across the screen.
I would love to see the option to have only specific notification sounds on, and being able to change the volume of the notifications.
