I would appreciate feature to disable automatic sync of files shared with me in desktop client.
Some files could be interested for occasional viewing, but not so important to me to sync them. Or I will need sync them selectively upon request.
Currently, you can only work around that, e.g. only sync a specific folder where you put all content you want to sync. Nextcloud does not do yet an independent client-development, there is just a theming for the owncloud client. There is already a feature request in their bugtracker: https://github.com/owncloud/client/issues/4446
