Often I get a note/article by its author and then later as an announce by someone else I follow or even from multiple people.
This fills up my stream/inbox and makes it harder to find new messages. It would be a nice feature to be able to choose to just have the first appearance of a note/article in Stream/Inbox.
Maybe this is already possible using the filter you describe on your instance ?
Hey, there's already an always-on dedup to prevent seeing multiple announces of the same object, but there's no nothing in place to prevent seeing announces of known objects.
I will check it it would be doable with filters or consider adding an extra setting for this.
