I read about a partnership with purism and nextcloud i whould like to know if will be a nextcloud talk app at launch
To use nextcloud in its simplest form, you only need a WebDav client, a CalDav client and a CarDav client. All those already exist in Debian.
A more advanced client (e.g. with lazy loading of the photos) might probably implemented later, although I am not aware of the terms of the partnership between Purism and Nextcloud
Should be lovely to have a native nextcloud talk app for librem without the need to use a browser instance, that is good for nextcloud but not really viable for talk on smartphone because of background notifications and other features
