Altify provides functionality which integrates with Salesforce Chatter. Using this functionality you can post updates on opportunities, view the message feed for that opportunity or share files and links with other users.
Click the Show Feed button at the top right of the screen.
To close the Chatter panel, click on the Hide Feed button.
Chatter Updates
When you edit and save information on a tab, an update is automatically posted to Chatter. To prevent large amounts of updates being generated if you make multiple edits, this function includes a time delay so that the next update for that tab is only posted after a specified length of time has passed. This time delay is configured using the Chatter Snooze setting which is set to 30 minutes by default.
