Sidebar in threads makes the posts all squeezed and can break formatting in some cases... Can you just make it optional or something? There's no point anyway for those that go through the portal often, especially since with a recent content box you can make the portal have pretty much everything in one place.

It is optional, head to preferences and find " Disable sidebar in thread view (in testing)"
