I’m not an employee of Firecore so I didn’t see what you posted on twitter, sorry. I think the language difference is what’s throwing me off a bit. When you say “Saga” do you mean collections for Plex? If so, that’s on the “Upcoming Features” post here in suggestions but it’s under the “Planned” heading so I’d guess it would be at least a few updates away since they have what’s in 5.9.2 and what’s in progress for the one after that.
I do know that Firecore is a little reserved in giving dates for future enhancements since it can turn into a nightmare when unforeseen problems in the software make them reschedule features for future releases. Then people get angry that they didn’t get that feature when promised. Sorry if I misunderstood.
