Apologies if this has already been suggested! Nothing similar turned up with a quick search.
Something I really enjoyed about older versions of Safari was how it would show an indicator in its address bar when a site had RSS/Atom feeds available (see screenshot), often in cases where the feeds weren't obviously advertised on the pages themselves. Clicking the indicator yielded a menu of feeds available for the site.
Subscribing to feeds is likely beyond the scope of Orion, but I think the address bar indicator that forwards feed URLs to the user's default RSS reader would be a nice feature to integrate. While this is possible with existing Chrome/Firefox extensions, it being a native feature would allow an extra degree of polish and eliminate need for an extension that has permission to see all site contents, as is necessary for extensions to be able to detect the presence of feeds.
