I often get complaints from users with complex document composition needs that once they break up their complex documents into a page hierarchy in Confluence (for maintainability and linkability), they can't easily print out the whole thing to read on on their commute as an example (or take an export of it for that matter). So it would be great if there was an easy to get a printable view of an entire page hierarchy. The current workaround I give them is to go to Browse Space -> Advanced -> Export space -> check, check, check... which quickly (and understandably) gets very old. This feature would therefore be a tremendous boost to adoption, as this limitation is one of the few reasons why people fall back to using MS Word for complex/long documents.
