There are always groups that you need more often. From now on, you can quickly find these groups via favourites in the group overview under the My Bookmarks filter:
There are two steps to favouriting a group. First, open the group you want to bookmark.
Then choose:
1. More options (...)
2. Save as favorite
The group has now been saved as a favourite. Do you want to undo this? Follow the steps above again, and in the second step, select Delete from favourites.
