In competing products, there is the ability to create “channels” within the inbox. This enables you to group tickets based on their status and activity e.g. open, closed, recently updated, spam, trash, unassigned, unsolved, pending, etc.
The interface gets messy because there is only one location for all tickets (granted you can filter). It would be nice to categorise tickets as per my above example. I would insert an image as an example, but there is currently a bug in your community topic creation.
