This is a neat idea that plays into the notion that we can’t 100% our feeds anymore and thus don’t need to see that we have thousands of unread RSS feed entries (and videos, and Reddit posts, and so on and on) we’ll never get to. As a complement to this app Classic (but, personally, not a replacement for it), I can easily see a use case that has me using both daily.
But I won’t pick this up again until there’s some visual indication of which posts I’ve read/seen/watched/heard. A syncing timeline isn’t enough (and, so far in my testing, not very reliable in terms of where it lands after a sync). I don’t need unread item counts or empty feed folders, but please just dim the items I’ve interacted with (or, better, give us an option to automatically hide those from the main feed once they’ve been interacted with). Without that option, this feels way more unwieldy than a large list of unread feeds in Classic, and I’ve only loaded up about four feeds so far.
A small fix, even if it’s off by default but available as an option, will go a long way.
