Imagine a world where you can click on one of your nearly infinite voicemails, then hitting ctrl-a (or just clicking on the 'select all' button).
Now you've got like 1,245 voicemails from jealous ex's, desperate vendors, and unrequited direct supervisors. They are all selected. Now absolve yourself from the weight of these disconnected communication attempts, tugging on the last threads of your sanity. When you select all, you don't even need to see who is calling. Just delete that BS. Get it gone from your life.
Catharsis in a button. Bonus points for the developer that adds a toilet flushing sound to the "Delete All Voicemails" button. This toilet only flushes. It never backs up. It can swallow anything.
