If all page elements / blocks would be widgets, then we would be able to order all page elements in any position we like. Not just sidebar blocks, but any page element. This will allow us to place any block anywhere. We could reorder page elements to our liking and easily create unique pages. It will also allow us to easily turn page elements off by deactivating the widget. Or replace a page element by sticking a new widget on the same location as the deactivated widget. Please consider to add this feature, as it will greatly enhance xenforo as a whole.
