Umm, I’m not sure as I didn’t use Sync for Reddit, if it was an app specific feature.
In the current Lemmy app if we hide read posts, they are kinda lost. I’d like to visit a community and even see the read posts that were hidden from the frontpage. It could be an option for the user to decide if they want the current method or let the hidden “read” posts be hidden only from the All/Subscribed/Local frontpage (and not from the community page itself)
Why choose this over DuckDuckGo? Genuine question as it has minimal tracking and is free.
