DMAIL - Finally a delete button for Gmail. Using this extension, you can revoke access to any message sent with Dmail at any time.
FOLDER NOTIFICATIONS FOR GOOGLE DRIVE - When someone makes a change to a Google document you shared, you want to know about it. Use this link to keep track of changes made to a file. You will receive an email every time a file in a specific folder is edited or new files are added to the folder.
I added these new extensions to the Potts' Favorite Chrome Extensions & Apps doc. If you haven't checked out the doc lately, click the above link to check out what's new.
