A notification sound when a task is completed.

One feature I’m really missing is from Microsoft ToDo.

When a task is completed a notification sound is played. It would be so nice if this is replicated in Monday.com. With Monday it can be when a task is put on the green finished field.

I completely agree with this! I use Slack regularly to communicate with coworkers on my team and the sounds make more of a difference than one would think! (P-PING!!)
