There are two ways you can access notifications in Productive.
Hover the Inbox with your mouse to get quick access to recent notifications
Click on the Inbox to open it up and work using the Inbox mode
Hover the Inbox
Hovering the Inbox will show you the most recent notifications in chronological order. If you want to open any notification, simply click on it.
If a notification has the blue @ symbol, this means that someone has directly @mentioned you, so you should probably keep an extra eye on this particular notification.
If the background is entirely blue, this is an unread notification. If the background is white, this is a notification you've already seen.
Clicking on the Inbox will expand it completely and keep it open at all times.
In the example above, you can see that the Inbox, once opened, also opens whatever the notification is for on the right. In this case, the first notification relates to a Firefox bug, which is a task that has immediately been opened on the right.
This helps you deal with tasks and other issues one by one, instantly skipping on the next issue in line when you archive the notification you're currently looking at.
If you want to get more details from the notification itself, turn off the Compact view, as seen below.
You can even filter notifications here.
Inbox = all notifications
Mentions = only notifications where you've been @mentioned
Archived = old notifications which you've archived can be found here
To archive a notification, click the button that shows up when you hover the notification itself.
