Hiding chat window + cursor
 

Is there a plugin which can hide the chat window in its entirety and another one with which I can toggle the visibility of the cursor?

Plugins cannot replace base UI elements so no on the chat window and the cursor.

You can hide the whole UI with a keybind the game has per default, but neither chat window nor cursor have that separately.

I dont think you can hide the chat completely. Not sure why you would want toggle visibility of mouse, if you dont want to see it, you can just position it on the edge of screen? However if you are having trouble finding your mouse cursor, there is plugin for it - https://www.lotrointerface.com/downl...useFinder.html
