Several ways to use columns. They aren't necessarily difficult to construct, but they complicate views on various devices. I see this as an advanced feature, not recommended for most users.

Page TreeChildren. Simply Simply lists pages in space. I strongly recommend this for the home page for each space. Indeed, we might make it the only allowable editable content on each space's home page, other than perhaps a welcome message. We should have this despite a page tree existing in teh sidebar and the "child pages" list below, because those are not visible in mobile. , as well as parent pages for offices. "Page Tree" purports to do the same thing, and we used it in the past, but it is not visible in the mobile browser version.
