What is the enhancement in mind? How should it look and feel?
Subgroups OR prefixes and suffixes work together from other groups you may have.
Please provide any additional information below.
Well, this would be amazing for prison servers because donators can have a suffix while they still keep their rank as a prefix.
Most people would want to have donators show their rank as a suffix and still show players their real rank as a staff or member.
How this would work?
In tracks, if a player is in 2 tracks and the rank he is has a prefix and the other has a suffix, both the prefix and the suffix would show.
