I've added a simple toggle feature on the "Newest & Updated stories" section in the Study area. Just click anywhere in the titlebar to show or hide the newest stories.

The newest stories will show again when you move to another kanji, that's intended: hiding stories permanently would defeat the purpose of the "newest" stories section; which is to give a chance to the new stories to get votes. The feature is there for when you scroll up and down a lot between shared stories and the edit area.
