Now how come paste dosn't work in this. If paste dosn't work then it's a usless addition

Are talking about the come-back message window?

If that's the case, paste (ctrl+v) does work in this window.
If you are talking about other thing, please explain more about your problem
You could start with your OS, version of the messenger client and the version of Plus!.

It works fine ¬_¬
