Me and @ProDev made an extension to have a custom Staff badge for certain users, the colors of this badge can be modified + the text.
composer require serakoi/flarumstaffbadge
These are some screenshots of the extension
On the admin page:
On the user page:
On user card:
You can activate the staff badge on a profile by clicking the 'Controls > edit
button, and setting theStaff Badge Enabled
totrue` (Will be made an actual toggle later ;") )
If you have any other suggestion then feel free to tell me!
