Discourse is great but there are times (too many) when the New/Unread numbers are way off. The hidden unseen page is better and is what I personally use on every Discourse installation I use including here by adding the word unseen to the basic URL like this https://forum.timeline.app/unseen
Over on NaNoWriMo that put that in a explicit link at the top of every page. Others have added to the hamburger menu.
Please this most useful but hidden feature be elevated here to help get around the way off numbers on New and Unread?
