#Feature request
Can you please add chat support? For prefixes in the chat That would be great! And please add a config entry to toggle the feature!
Sorry for my bad englisch!

We use to have chat support. However, we removed it. But, this can actually still be accomplished through using Vault, DeluxeChat, and PlaceHolderAPI. This also depends on your permission plugin, I use zPermissions.

In the NametagEdit Configuration, you would set up %vault_prefix% on all the ranks.

formats:
  default:
    priority: 2147483647
    channel: ''
    prefix: '%vault_prefix%'
    name_color: '&f'
    name: '%player_name%'
    suffix: ' &e> '
    chat_color: '&f'
    channel_tooltip:
    - ''
    prefix_tooltip:
    - '&3&lName &e&l>&r %player_name%'
    - '&3&lRank &e&l>&r %vault_prefix%'
    name_tooltip:
    - '&3&lMoney &e&l>&r %mvdw_money_rounded%'
    suffix_tooltip:
    - ''
    channel_click_command: /ranks
    prefix_click_command: /ranks
    name_click_command: '/msg %player_name% '
    suffix_click_command: ''

Don't forget the pemission node chatformat.default

Download PlaceHolderAPI:
https://www.spigotmc.org/resources/placeholderapi.6245/

Once loaded you need to run the following commands:

/papi elcloud download vault
/papi ecloud download player
/papi ecloud download mvdw

Restart your server. Do not /reload

Now your wondering where do the ranks come from? That's in the permissions plugin I use, I'm sure all permission plugins support this:

/perm group NAME create
perm group OWNER prefix '&4&lOWNER &r'

The %vault_prefix% can be used anywhere that PlaceHolderAPI or mvdw supports. Example, FeatherBoard, and tab-based plugins.
