The speed of how new useful functionalities in Microsoft Defender XDR, previously Microsoft 365 Defender, are being developed is very high. From this perspective it is super important to send feedback, not only things that may not work as you expected or if there is an error, but also new feature requests.
Some new features which was released in GA in February is within the incident management space.

Change incident severity
When a incident is being generated, the severity is based on the alert with highest severity. If the severity is wrong, you can change it by opening the manage incident which will open the incident pane.
Assign incident to a group
Instead of only assign the incident to a specific individual (who might be on a leave), it is now possible to assign the incident to a group by opening the manage incident which will open the incident pane.
Go hunt directly from attack story

When selecting an item in the attack story, you will get an option for “Go Hunt” which will give you the options to choose between All activities, Related alerts and See all available queries
When selecting a query, you will have the response in the same window. The positive thing with this is that you don’t have to move away from the incident view. If you want to continue the hunting you have the option to “Open in advanced hunting”

Happy Hunting!
