Hi, is it possible to add an api for this plugin please ? To trigger it with another plugin :)

What exactly would the "API" be? Any plugin can call another plugin's methods, but there isn't really any point in an "API" in this plugin. If you want to rename a player, the other plugin can use the same methods that this plugin uses from Oxide's API.

I would rename player after death (for rp), but i don't found in your plugin where does exactly rename appears :/

The actual rename is being handled by Oxide using the IPlayer.Rename API method. 

Uhh okay, thank you very much !
