It's hard to acsess the forums without a navbar button. Same for the Wiki.
Describe the solution you'd like
I propose a addon that adds a Wiki button to the navbar, just like Maximouse and World_Language's Discuss button.
furthermore, when addon options get advanced enough #255, being able to create your own navbar would be cool.
I actually thought about this for a while, because this is also an MSU feature. This featured could be implemented inside the "Discuss button" addon. I also wanted to change the name and the ID if this got a green light, since the options are quite simple, but I'm not sure if it's actually okay.
EDIT: Here's a screenshot of both SA's "Discuss button" and MSU's "Wiki Button" running.

Why not just the ability to have a custom url for the button? Maybe even the ability to add multiple buttons?
I'd suggest a dropdown that has links to the Wiki and the Discussion page so that people with small screens won't have their navbar cluttered. Just an idea.
