Yeah it seems you can only set them as inbox, outbox and/or DMs, but not as only read/discovery/search as you can in nostrudel or gossip. The result for me is that the feed is really "unstable", if I reload the page it keeps giving me posts in different orders and most of the times some are missing, and even if I select replies for the feed, sometimes I dont see posts I should see and I need to disable and reenable the replies button (not 100% sure this solves the "problem"). I tried a lot of clients, but for me only nostrudel and gossip displays all the events, but I am not sure this is only related to relays management. Coracle UI is super cool though.
