No. This plugin will only focus on permissions. Chat prefixes and suffixes are not related to a permission plugin.
This is not PermissionsEx, and this plugin will not have a chat plugin feature because it’s not related to this.
If you want to use this plugin and have chat prefixes/suffixes, you can use [WIP] Chaton 3.0.0 - Customize your server chat (I haven’t tested it, I just did a fast search on the forum). You can assign a prefix/suffix to a player by setting to the player/group a specific permission.
