Cloudron is missing apps for most use cases I actually care about.

Can you add a google photos type app? Maybe Piwigo (it has a good mobile app) or OwnPhotos[1] (it has face/object recognition). Lychee doesn't have a mobile app or face/object recognition.

Can you add some communication apps like Matrix Synapse or Ejabberd? Mattermost is walled off from the outside world.

Can you add some social apps like Pleroma or Mastodon?
