Removes all Gmail labels currently.
USE IT AT YOUR OWN RISK! Click on the icon. If you are not in the Gmail settings label page, a pop up will warn you. If you are in the right page another pop up will warn you about the fact that this extension will delete all your labels. I needed to remove all labels from an imported Outlook PST that contained over 1000 labels. I created this extension to aid on migrating corporate users from Outlook into Gmail.
