Avatars Only display style spacing has been fixed - 2px gap between each avatar.
Usernames + Avatars display style has been added.
Add-on / Widget titles have been updated to include [Sysnative].
Usersnames and Avatars
Note: This has been tested with the default XF theme, however I've noticed that display styling for Usernames + Avatars can be slightly odd for custom themes. Unfortunately I wasn't able to identify a consistent cause, so this may need to be customised in your theme specifically to make sure username/avatar alignment works correctly.
