I would really love to be able to Ctrl or Shift Click to select multiple items in my feed (or even just use an old fashioned check box) so I could select either Mark as Read or Mark as Unread. I understand that you have chosen to limit the number of unread articles per account (though don't really understand why) but to stay on top of feeds, bulk editing is therefore very necessary. Others have suggested bulk actions, but marking unread is as important if you're going to artificially enforce "mark as read" on articles I haven't, actually, read!
