What's in your feature wishlist?

I’m not sure if this is a bug or a feature request, but I can’t seem to turn off the desktop notification sounds for RTX. I didn’t find any RescueTime settings regarding that, and I’ve turned off all of the settings in Windows that I can think of. I like the notifications, but don’t want the sounds. Is this something I can fix myself, or a bug?
Images of my current desktop notification settings attached - one is for all notifications, and one is specifically to control RescueTime.
