i'm still doing the first steps regarding xenforo. Pretty happy with it so far.
What i would need is an Add On for the sidebar. Administrators should be able to add thread related content in the sidebar.
If there's a thread about a book - for example - there should be the possibility for administrators to link the amazon site of the book in the sidebar, or an article about it.
How much effort would it be to make an addon to achieve that? Are there already related AddOns that could help at its creation?
