I used to use Google Reader to read my RSS feeds. It has been shut down, so that is no longer an option. One very useful feature that it had was a bookmarklet that took me to the first unread item in the feed.
I am currently using Feedly which does not appear to have such a feature. Searching google found many people saying that it would be great to have one, but nothing indicating that it exists.
Is there a reader with such functionality? I am not strongly attached to Feedly and will happily move elsewhere if another service has this feature.
