Welcome to the thread @ByteHamster!
Yes, exactly!
You seem to be making the assumption that New/Inbox can always be cleared in every sitting, when in fact new episodes might occasionally be coming in at a far too great pace for that.
Please compare this with how email is used. Some people tend to reset messages’ statuses to unread, until having had a chance to act on each one. Coretex has even had lengthy discussions about how being able to peek without changing read status is a deciding factor for some people when selecting email client. I believe manageability of the New/Inbox state should be considered a user expectation. So far I have not really seen any motivation to why that can not be made possible. I am fully aware it is currently not being implemented that way, and that any decision to allow a change will require (duh!) actually making changes.
That is not practical for at least a couple of reasons. Some podcasts are to be cherry-picked, lets get back to those. Even for the simple case where the entire backlog is interesting; adding hundreds of episodes to the queue creates the bigger problem of constantly needing to reorder the queue. Months or years might be required to clear the backlog of one single feed, and practically there is probably more than one such source to slowly progress through, all while trying to stay on top of other feeds listened to in real-time as new episodes are released.
Regarding cherry-picking. Please consider e.g. BBC’s desert island discs which has 2k5 episodes available to podcast, from eight decades of broadcasting. Few people would listen to all of those, but still it is the type of material which people find relevant to listen to selected parts of. Proof: podcasting wasn’t a thing in 1942, but BBC has bothered to make all these available. Is the recommendation for anyone wishing to sift through that treasure trove to add five years to the queue at a time? Do you truly find that to correspond to what makes AntennaPod more attractive than BBC Sounds? We have similar programs with timeless material from other public service broadcasters, and people do have interest in listening through such old material. Wouldn’t it be desirable if AntennaPod made that experience as pleasant as possible?
If putting the user experience first, rather than being fixed at never allow changes to the current functionality, would it then not make sense to allow adding to Inbox/New? If not, I would really wish to understand the rationale behind why that suggestion does not seem to at all be considerable.
