XF 2.1 Sidebar On / In Thread List - Possible?


Well-known member
I thought I must just be blind... but I can't find a way to setup a sidebar and widgets in the thread lists. I've searched Xenforo directly (and indirectly via Google search), but haven't found anything.

(for example, this view: https://xenforo.com/community/forums/xenforo-suggestions.18/ )

So my questions:
  1. Is it really not possible / part of the core XF to have the ability to enable the sidebar on the list of threads within a forum?
  2. If not, are there any addons that provide for this?
Thanks guys!
