Usability changes Increase darkenss of footer. Insufficient contrast using lightgrey, change to grey which is still subdued compared to black but has more contrast against white background. Add aria-labels to search/jumpto fields whose labels are contained in the buttons that submit the form. Add aria-label to password field.
