Four small options, all in Settings, all off until you turn them on: • Undo for Mark all read. A button shows for a few seconds so you can take it back. • Every shortcut in the key strip. Adds "a" (add a source) and "r" (refresh) to the row under the list. • Refresh when you return. Tilde checks your sources when you come back after a few minutes away. • Dock badge. Your unread count on the Tilde icon in the Dock. If you change nothing, Tilde works exactly as before. Your feeds, saved articles and read state are untouched.
