Recently I needed to sort invisible pages.
There are some different ways to handle this but they all feel kind of hacky or add unnecessary bloat.
I suggest a different naming convention for visible and invisible pages.
Visible pages
The order for a folder should be seperated with a _.
/content/1_projects
/content/2_about
/content/3_contact
Invisible pages
Folders starting with a _ are invisible. No matter if they have a order or not.
/content/_terms-of-service
/content/_imprint
Or when you need to sort those pages.
/content/_4_terms-of-service
/content/_5_imprint
Another benefit would be to have invisible pages like _03-whatever. Currently not possible.
By checking the filename for any underscores it would be possible to detect if a folder uses the current or this naming convention. So not all sites would break when kirby gets updated.
There was a similar Topic a year ago or so but i was not able to find it yet.

Edit:
Found it. The topic was different than expected
