The new “read stories” feature was a useful addition, to view the history of stories we’ve actually read (e.g. to make it easier to go back to an article we recently read, instead of hunting through all the folders to find it or use the search tool).
However, it would be nice for users to have the ability to purge that history periodically (e.g. for privacy or security reasons). A right-click over the “Read Stories” doesn’t bring up any menu at present. Perhaps adding a menu item that allows one to clear all the items from that section might be easy to do.
