Click "New Stat Group" and give it a Name. The key setting is Categories — choose which object types the group appears on (Characters, Entities, Places), so the same stats can be reused across features. A group with no categories shows nowhere. Game Masters also get Secret? (hides the group from players) and Private? (visible only to the profile's owner and GMs). You can sort the group into a Stat Group Folder to keep the admin tidy.

Each group row has a blue "View Stats" button and a green Edit pencil; deleting is done from the edit window.

Stat Group Folders

The admin sidebar organizes your groups into folders, with All Stat Groups and Unsorted Stat Groups views. Game Masters and Stat Managers can create and manage folders with the blue "Manage Folders" button; deleting a folder never deletes its groups (they just become unsorted).
