This has been reported (I believe) since 2017:
That static page folders in root position which supposedly can be dragged to a new position do not do so. I really hope this gets fixed soon.
As you consider fixes, for all things whereby it would default to a natural alpha/numeric order, that would be wonderful: folders, symbols, etc.
Other than that! Wonderful!
PS: The ability to have folders for CMS Template pages is already registered as a “wish” item.
I agree…but if it were ever possible to bring everything within one category (all static and CMS Collection files and Templates) so that everything is within the same area of the page it would be great!)
