hello could you add text editing to the config for possible translations and changing the color of the text?

Yes this is planned eventually

Done in 1.2.0

Okay, but could you add a second sentence Empty hand message ?
and how to use color codes? simple §3 ?

Oh sorry I forgot about the failure message
and yes thats the only way to do it

Done in 1.2.1

you are super fast in support I appreciate it.. after today testing everything works great but I encountered a problem with the fact that in the config can not color player_name and item_name .. after coloring they remain in the chat white

How did you try to color them

chatMessage=§8§l[§c§li§8§l] §6%player:displayname% §ezaflexil s §6%itemflexer:item%

Seems like an issue with the API im using, cant do anything about it sorry
