Multi-select for marking read, unread, or to delete.
Metadata export and import, much like you can do with Newpipe to instantly move all your data to a new instance.
Tor support but not enabled by default. I don't need tor for rss (yet) and don't want my rss app having to double tunnel (as I run a VPN 24/7).
Media-less option selectable by individual feed. You can be tracked by autoloading media at times.
Simplified viewing option.
Assignable hot keys for user selected options.
