It has occurred multiple times where I thought I have sent an important email, but rather than sending, the email has instead simply been retained unsent in my drafts, perhaps due to connectivity issues. I propose an idea for a draft notification feature, where users get notified of drafts that have been untouched for more than a certain period of time (perhaps 2 days?), allowing us to identify important messages that may have accidentally been left unsent. This also makes uncluttering drafts easier. Users can also edit their draft notification period length for any given drafts or turn them off entirely.
