I see that development isn't very active these days, but let me congratulate you with new site! =) Anyway I would like to land a feature proposal.
Please, consider options that let users read the messages via desktop Gnome. I don't know what services are available to a F-droid app in Android, but people would be happy to receive texts in their mail or Jabber, even when directly added (inside system) to @K-9 Mail
inbox, or a Conversations channel.
