Well because of the new navbar it won't say if you have a new message or not.
How will you know?
Allow pop ups and when you get a PM it will bring a pop up telling you.

Hopes this helps some people.

I'll try to make it where it says "Inbox 1" and it counts the PMs you have but that might take a while to get done.

Cool, there's a way for it to do that. I might try and help find the code.

I've been looking for a JS code. Found one but it didn't work lol.
