Small customizations

See also static_dir.md for visual settings.

Theme

All users of your instance will be able to change the theme they use by going to the settings (the cog in the top-right hand corner). However, if you wish to change the default theme, you can do so by editing theme in config/dev.secret.exs accordingly.

Message Visibility

To enable message visibility options when posting like in the Mastodon frontend, set scope_options_enabled to true in config/dev.secret.exs.
