There’s now a subscription management page that allows you to unsubscribe from/move your subscriptions. You can get there by clicking on “Subscriptions” in the user name dropdown in the upper right.
I don't know what would be less time-consuming work for them:
1- nesting folders, or
2- tags as folders
but either one would allow to manage/view subscriptions in more or less fine-grained grouping
title should be "Manage Folders and Feeds"
just a comment: the post title already links to the original article (as the feed links it) and the keyboard shortcut "V" does it as well
One intermediary step could be:
- when scrolling calls the event to load more items, remove some(1) of previously read/loaded items or all of them and keep only those new/unread .
1- if I counted it correctly, there are 30 posts per load, so the mechanism would load the new 30 and some here could mean the last 5 or 10 posts from previous load.
