@MAHDOOD we do have plans to implement an option like this, however this is not a basic feature. Also, seeing as most users would rather only be notified when being replied to directly, this is not a priority for us. Please stay tuned for future updates that could potentially carry this feature.

Long reply threads are the bane of Nostr client devs because they're hard to implement, but I do believe that people would like to talk to the people taking the time to respond under their notes, even if those replies are nested under the direct replies. And if a sub thread really is uninteresting, to be able to mute all replies under one of your replies would be godsend. But if Primal's primary customers really are just legacy platforms influencers, then I can see why it's not a priority. Those users typically don't want to talk to their followers, but would rather farm the engagement and the zaps. Who cares if they're not notified of people having conversations. Those aren't valuable to the influencer except to run through an AI to gain some sentiment metrics or keywords.
