Hi friend!
I did try to implement it, but it was too confuse to put that inside that plugin and I give up. I don't have a Message Log plugin, maybe I can try make it someday. But for now, I'm too busy to start creating one. Also, this plugin needs a serious rewrite, because it depends on the default Message Window code. I want to create it in a way that it does not depend on that. This will give me more freedom to create other things on that plugin, and also, more compatibility with other plugins around.
Sorry about that. If I ever do a plugin like that, I will give you a free key ^^
