hey @SlackHQ please please make it possible that we can upload our own notification sounds. i respect your choice of sounds, and for the longest time they were fine, but recently i have grown to hate them all. i need a sound that is less urgent, less disruptive.
While it's not something we're currently working on, we can see how it would be useful, Peter. We'll pass the idea on to the team to consider — thanks for the nudge.
