Productive

Productive makes it easy to keep track of the hundreds of messages you get every day! Add your important messages to your backlog so you don't forget them later.

For the sake of privacy, backlogs are confined within guilds. The backlog you create within a guild will only be visible within that guild. However, you can send the /backlog command in DM to get a list of all your backlogs in all guilds.
