For our apps outside of Nextcloud we’ve been looking at having support for users to save their files to Nextcloud. Of course this is possible through loginflow and webdav file upload. However, we were also looking into having a file interface that would let the user select where they want to save the file, create new folder to save it, etc.
Basically similar to how it is when you try to save a document on your PC. There are already similar integration to other file storage services (such as onedrive) and it should be possible in Nextcloud because it has webdav.
Does anyone know any webdav type applications that one could integrate with their own to not have to create an entire filepicker interface from scratch?
