USAGE

Press O to open the overlay changer GUI(you can change this later in your controls)

Enter your text to obviously, change the watermark

(Fun fact, it stores the text in %appdata%\.minecraft\overlaytext.txt so it remembers the text you put in

You can enable and disable the overlay using /disableoverlay and /enableoverlay

Aaaand...that's it :3

I don't know anyone who would use this though...
