How can I change the font in the message block? I gave this plugin to the coder, but he refused to do it, referring to the poor quality assembly of the plugin. Author, please help.

What coder ?, and i suppose you will have to wait for his/her more magnificent plugin (?) but in the meantime i dont believe that there is any function to change the font,  you can change the colour and size and make it bold and or italic but that is as far as you can go,
If i am wrong i am sure someone will point it out,

It is enough for a developer to register fonts in the plugin code to make everything work.

You said you "gave" this plugin to the "coder" ? , not the author and as far as i can see it works 100% ,
