My client has a need to organize the pages in the CMS tree into folders without affecting page routes. Currently the root is more or less cluttered with pages and they expect it to increase over time. If there was a possibility to create folders to hide more or less inactive items it would be easier to overview the page hierachy and find what you're looking for.
I have also a related forum post about this: https://forum.litium.com/t/cms-folder-without-affecting-page-route/2398
