Someone may have already suggested this, but having an alarm for things like preheating extruders and beds would be great.
An alarm for job finished would also be nice

If your machine has a buzzer on it, such as the LCD screen, there's a command that will play a beep.

Play beep sound, use to notify important events like the end of printing. See working example on R2C2 electronics.

I just tested it on my Taz 4 and it beeped at me!

You can add this to the the Starting scripts and ending scripts to give you a notification when it finishes preheating and finishes printing.
