Duo Strength is a browser extension that adds back into the Duolingo webpage an indication of the strength of each skill. Any skills that need strengthening (i.e. not at 100% strength) are displayed in a clickable list at the top of the tree for quick access. Designed to provide much of the information on duome.eu/Username/progress on your duolingo tree itself.
