wishing for a better integration in the files app

[KnifeOfDunwall]

Hi, using nextcloud on the os's i use is really nice but i want to add my mother to the setup.
She only has ios devices and the options in the files integration seem rather limited. While you can see stuff as available in the webpage sometimes folders show as empty despite being populated on the server.
Marking folders for offline view is not possible, only files however removing the files from the local device once downloaded also seems cumbersome. They dont show up in the offline files for the actual app and the only way to get rid of them seems to be to delete all of them with the clear cache button
Is there a way to streamline it by adding a mark and unmark menu option for offline in the files integration?

Thanks
